Question

# Solve 3(x − 7) = 2(x − 3). Write a reason for each step.

Hint:

### using the additive property and subtraction property ,division property on both sides .solve for x.

## The correct answer is: x = 15

### Ans:- x = 15

Given ,3(x − 7) = 2(x -3).

By left distributive property 3x - 21 = 2x - 6

Adding 21 on both sides by additive property of equality both sides remain equal.

3x - 21 + 21 = 2x - 6 + 21

3x = 2x + 15

Subtract 2x from both sides by subtraction property of equality both sides remains equal.

3x - 2x = 2x +15 - 2x

x = 15

∴x = 15
