# How much greater is the value of 3x + 5 than the value of 3x − 7?

We will use the concept of subtraction of algebraic expressions in order to find the value.

## Answer: 3x + 5 is greater than 3x - 7 by 12 units.

Let us see how we will use the concept of subtraction in order to find the value.

**Explanation:**

We have been given two linear equations that are 3x + 5 and 3x − 7.

In order to find how much greater is the value of 3x + 5 than 3x − 7, we have to subtract 3x - 7 from 3x + 5.

Hence, on performing subtraction of 3x - 7 from 3x + 5 we get,

3x + 5 - (3x - 7)

⇒ 3x + 5 - 3x + 7

⇒ 12 units
