Let's consider the equation:
This equation presents a classic algebraic puzzle, challenging us to isolate the variable 'x' and determine its value. The solution process involves a series of steps, each carefully designed to manipulate the equation while maintaining its balance. To fully grasp the solution, we must not only execute the steps but also understand the mathematical justifications that underpin them. In the following sections, we will dissect the solution, scrutinizing each step and revealing the logical principles that guide it. This approach will empower you to not just solve the equation but also to comprehend the 'why' behind each manipulation, fostering a deeper understanding of algebraic concepts. The importance of understanding the 'why' cannot be overstated, as it transforms rote memorization into genuine comprehension, enabling you to apply these principles to a wide range of mathematical problems.
H3: Step 1: Isolating the Variable Term
The initial equation is:
Step 1 of the solution process transforms this equation into:
The key to understanding this step lies in recognizing the addition property of equality. This property states that adding the same value to both sides of an equation preserves the equality. In this case, we subtract 12 from both sides of the original equation:
Simplifying both sides, we get:
This step effectively isolates the terms containing 'x' on one side of the equation, bringing us closer to our goal of solving for 'x'. By applying the addition property of equality, we maintain the balance of the equation while strategically manipulating its form. Understanding this principle is crucial for navigating the solution process and ensuring the accuracy of our results. The beauty of algebra lies in its precise rules and properties, which allow us to transform equations while preserving their fundamental truth. This step exemplifies that principle, showcasing how a simple subtraction, grounded in a fundamental property, can significantly advance the solution.
H3: Step 2: The Critical Transformation
Now, let's examine the crucial Step 2. We begin with the equation obtained in Step 1:
Step 2 then transforms this into:
The question at hand is: what is the justification for this transformation? The correct answer, as we will demonstrate, lies in the clever application of the addition property of equality once again. To eliminate the '7x' term from the right side of the equation, we add '-7x' to both sides:
Simplifying both sides, we combine like terms:
Thus, the justification for Step 2 is the addition property of equality. By adding the same value (-7x) to both sides, we maintain the equation's balance while strategically simplifying it. This step highlights the power of the addition property in manipulating equations and isolating the variable. It's a testament to the elegance and efficiency of algebraic techniques. The ability to recognize and apply these properties is paramount for success in equation solving. This step serves as a clear illustration of how a seemingly simple operation, when rooted in a fundamental principle, can drive us closer to the solution.
H2: Distinguishing the Properties of Equality
To fully appreciate the justification for Step 2, it's essential to distinguish between the different properties of equality. While the addition property of equality played a pivotal role in Step 2, other properties, such as the multiplication property of equality, are also frequently used in equation solving. Let's briefly explore these properties to clarify their roles and prevent confusion.
H3: The Addition Property of Equality: A Closer Look
As we've seen, the addition property of equality allows us to add the same value to both sides of an equation without altering its solution. This property is not limited to adding constants; we can also add variable terms, as demonstrated in Step 2. This flexibility makes the addition property a versatile tool in equation solving. It allows us to strategically manipulate equations to isolate variables and simplify expressions. The key is to identify the term that needs to be eliminated and then add its opposite to both sides. This technique forms the basis of many algebraic manipulations and is crucial for mastering equation solving. The addition property's simplicity belies its power; it's a fundamental principle that underpins a vast array of algebraic techniques.
H3: The Multiplication Property of Equality: A Different Approach
The multiplication property of equality, on the other hand, states that we can multiply both sides of an equation by the same non-zero value without changing its solution. This property is particularly useful for eliminating coefficients or clearing fractions. For instance, if we have the equation '2x = 6', we can multiply both sides by 1/2 (or divide by 2) to isolate 'x'. While the multiplication property wasn't directly used in Step 2 of our example, it's an equally important tool in the equation-solving arsenal. It complements the addition property, providing another avenue for manipulating equations and achieving our goal of isolating the variable. Understanding the nuances of both properties and knowing when to apply each one is key to becoming a proficient equation solver. These properties are the bedrock of algebraic manipulation, and mastering them is essential for success in higher-level mathematics.
H2: Mastering Equation Solving: A Path to Mathematical Fluency
Solving equations is not merely a mechanical process; it's an exercise in logical reasoning and a demonstration of mathematical understanding. By grasping the justifications behind each step, we move beyond rote memorization and develop a deeper appreciation for the elegance and consistency of mathematics. This deeper understanding empowers us to tackle more complex problems and apply our knowledge in novel situations. The journey to mathematical fluency is paved with understanding, not just memorization. By focusing on the 'why' behind the 'how', we unlock a world of mathematical possibilities and develop a true command of the subject.
This exploration of Step 2 in the equation-solving process highlights the importance of the addition property of equality. By understanding this fundamental principle, we can confidently navigate algebraic manipulations and arrive at accurate solutions. Remember, mathematics is not just about finding the answer; it's about understanding the process and the reasoning behind it. By embracing this approach, you'll not only become a better equation solver but also a more confident and capable mathematician. The journey of learning mathematics is a journey of discovery, and each step, when understood, brings us closer to a deeper appreciation of this powerful and beautiful subject.
H2: Reworded Question for Clarity
Instead of simply asking "What is the justification for step 2 in the solution process?", a more user-friendly and clear question would be:
What mathematical property justifies the transformation from -x = 7x + 20 to -8x = 20 in the provided solution?
This reworded question directly asks for the mathematical property, making the intent clearer and guiding the respondent towards the correct type of answer. The original question was valid, but the revised version enhances clarity and precision, making it easier for someone to understand what information is being sought. Clarity in questioning is paramount in mathematics, as it ensures that the respondent focuses on the core concept being assessed. This minor refinement exemplifies how careful wording can significantly improve communication and understanding in a mathematical context. The goal is always to make the question as unambiguous as possible, leaving no room for misinterpretation and ensuring that the respondent can effectively demonstrate their knowledge.
