Introduction

Linear equations are a fundamental concept in mathematics, and solving them is a crucial skill for students to master. In this article, we will explore the concept of equivalent equations and provide a step-by-step guide on how to match each equation with its equivalent counterpart. We will also discuss the importance of understanding linear equations and provide examples to illustrate the concept.

What are Equivalent Equations?

Equivalent equations are equations that have the same solution, but may look different. In other words, if two equations have the same solution, they are equivalent. For example, the equations 2x + 3 = 5 and x + 1.5 = 2.5 are equivalent because they both have the same solution, x = 1.

How to Match Equivalent Equations

To match equivalent equations, we need to follow a step-by-step process. Here are the steps:

Step 1: Simplify the Equation

The first step in matching equivalent equations is to simplify the equation. This involves combining like terms and eliminating any unnecessary variables.

Step 2: Isolate the Variable

Once the equation is simplified, the next step is to isolate the variable. This involves moving all the terms containing the variable to one side of the equation and the constant terms to the other side.

Step 3: Compare the Equations

After isolating the variable, the next step is to compare the equations. If the equations have the same solution, they are equivalent.

Examples of Equivalent Equations

Let's consider the following examples:

Example 1: x + 7 = 1

To match this equation with its equivalent counterpart, we need to simplify the equation by combining like terms.

x + 7 = 1
x = -6

The equivalent equation is x = -6.

Example 2: 2x + 15 = 3

To match this equation with its equivalent counterpart, we need to simplify the equation by combining like terms.

2x + 15 = 3
2x = -12
x = -6

The equivalent equation is x = -6.

Example 3: 4x = 8

To match this equation with its equivalent counterpart, we need to simplify the equation by combining like terms.

4x = 8
x = 2

The equivalent equation is x = 2.

Conclusion

Matching equivalent equations is an important skill in mathematics, and it requires a step-by-step approach. By simplifying the equation, isolating the variable, and comparing the equations, we can determine if two equations are equivalent. In this article, we have provided a guide on how to match equivalent equations and have discussed the importance of understanding linear equations.

Final Answer

Based on the examples provided, the equivalent equations are:

x + 7 = 1 and x = -6
2x + 15 = 3 and x = -6
4x = 8 and x = 2
