Question

# Solve 3(5x + 1) = 2(x + 21). 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 = 3

### Ans:- x = 3

Given ,3(5x + 1) = 2(x + 21).

By left distributive property 15x + 3 = 2x + 42

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

15x - 2x + 3 = 2x + 42 - 2x

13x + 3 = 42

Subtract 3 from both sides by subtraction property of equality both sides remains equal.

13x + 3 - 3 = 42 - 3

13x = 39

Dividing 9 by division property of equality both sides remains equal.

x = 3
