# Subtraction Property of Equality – Definition with Examples

Are you ready to dive into the wonderful world of math and explore the fascinating concept of the Subtraction Property of Equality? If you’re a young math enthusiast looking to expand your knowledge, you’ve come to the right place at Brighterly! In this article, we will uncover the definition of the Subtraction Property of Equality, discuss its formula, provide verification techniques, and even tackle problems involving fractions. So let’s embark on this mathematical journey together.

## What is the Subtraction Property of Equality?

The Subtraction Property of Equality is a fundamental principle in mathematics that allows us to manipulate equations involving subtraction. Simply put, it states that if you subtract the same quantity from both sides of an equation, the two sides remain equal. This property is an extension of the more familiar Addition Property of Equality, which deals with addition operations.

## Subtraction Property of Equality Definition

The definition of the Subtraction Property of Equality is straightforward. Let’s say we have an equation: a – b = c. According to the Subtraction Property of Equality, if we subtract b from both sides of the equation, the equation remains balanced. Therefore, we obtain: a – b – b = c – b, which simplifies to a – 2b = c – b.

## Subtraction Property of Equality Formula

To summarize the Subtraction Property of Equality in formulaic terms, we can express it as follows:

If a = b, then a – c = b – c.

This formula illustrates that we can subtract the same quantity (c) from both sides of an equation (a and b) while preserving their equality.

## Verification of Subtraction Property of Equality

You might be wondering, “How can we verify the Subtraction Property of Equality?” Well, it’s quite simple. Let’s consider an equation: 6 – 3 = 9 – 6. By applying the Subtraction Property of Equality, we can subtract 3 from both sides of the equation, resulting in 6 – 3 – 3 = 9 – 6 – 3. Simplifying further, we have 6 – 6 = 9 – 9, which is true since both sides of the equation equal zero. Thus, we have successfully verified the Subtraction Property of Equality.

## Subtraction Property of Equality Including Fractions

The Subtraction Property of Equality is not limited to whole numbers; it extends to fractions as well. Let’s examine an example: 2/3 – 1/3 = 4/6 – 2/6. By subtracting 1/3 from both sides of the equation, we get 2/3 – 1/3 – 1/3 = 4/6 – 2/6 – 1/3. Simplifying, we obtain 2/3 – 2/3 = 4/6 – 3/6, which equals zero on both sides. Hence, the Subtraction Property of Equality remains valid even when dealing with fractions.

## Practice Problems on Subtraction Property of Equality

To reinforce your understanding of the Subtraction Property of Equality, let’s tackle a few practice problems:

- Solve the equation: x – 7 = 15.
- If a – b = c, find the value of b in the equation 2a – 3b = 5c.
- What is the solution to the equation: 4 – (2x – 5) = 1 + (3x – 2)?
