# Use Properties To Rewrite The Given Equation

## Introduction

When solving equations in mathematics, it is often necessary to manipulate the equation using various properties to simplify it or to solve for a specific variable. Understanding how to use properties to rewrite equations is a crucial skill in algebra and beyond. In this article, we will explore different properties that can be used to rewrite equations, and we will provide examples to demonstrate how these properties can be applied.

## List of Properties to Rewrite Equations

• Commutative Property: This property states that changing the order of the terms in an addition or multiplication equation does not change the result. This property can be used to rearrange terms in an equation to simplify it.
• Associative Property: The associative property states that the grouping of terms in an addition or multiplication equation does not change the result. This property can be used to regroup terms in an equation to simplify it.
• Distributive Property: The distributive property states that multiplying a number by a sum results in the same answer as multiplying the number by each addend and then adding the products. This property is useful for expanding or simplifying expressions.
• Identity Property: The identity property states that adding 0 to a number does not change the value of the number, and multiplying a number by 1 does not change the value of the number. These properties can be used to simplify equations.
• Inverse Property: The inverse property states that adding the opposite of a number cancels out the number, and multiplying a number by its reciprocal gives 1. These properties can be used to simplify equations.

## Examples of Using Properties to Rewrite Equations

### Example 1:

Given the equation: 2x + 3 = 9, we can use the properties of equations to rewrite it.

• Using the Inverse Property, we can subtract 3 from both sides to get: 2x = 6.
• Then, using the Inverse Property again, we can divide both sides by 2 to solve for x: x = 3.

### Example 2:

Consider the equation: 4(y – 2) = 8.

• Using the Distributive Property, we can distribute the 4 to both terms inside the parentheses to get: 4y – 8 = 8.
• Next, we can add 8 to both sides using the Inverse Property to simplify the equation to: 4y = 16.
• Finally, divide both sides by 4 using the Inverse Property to find the value of y: y = 4.

## Conclusion

Using properties to rewrite equations is a fundamental skill in mathematics that can help simplify equations and solve for unknown variables. By understanding properties such as the commutative, associative, distributive, identity, and inverse properties, you can manipulate equations to make them easier to work with. Practice applying these properties to different equations to solidify your understanding and improve your problem-solving skills.
