# What is the value of x in the equation 7x + 2y = 48 , when y = 3?

**Solution:**

Given: Equation is 7x + 2y = 48

When y = 3

7x + 2 (3) = 48

By further calculation,

7x + 6 = 48

So we get,

7x = 48 - 6

On subtraction,

7x = 42

Divide both sides by 7 using the division property of equality

7x/7 = 42/7

x = 6

Therefore, the value of x is 6.

## What is the value of x in the equation 7x + 2y = 48 , when y = 3?

**Summary: **

The value of x in the equation 7x + 2y = 48 , when y = 3 is 6.
