Question

# Solve x − 11 = 2x + 9. 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 = - 20

### Ans:- x = - 20

Given , x − 11 = 2x + 9.

Adding 11 on both sides by additive property of equality both sides remain equal.

x – 11 + 11 = 2x + 9 + 11

x = 2x + 20

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

x - 2x = 2x + 20 - 2x

- x = 20

Dividing -1 by division property of equality both sides remains equal.

∴ x = - 20
