Answer:

x = -1

Explanation:

7x + 5(3 - 2x) = 18

Distribute 5 into (3 - 2x)

7x + 5 X 3 - 5 X 2x = 18

7x + 15 - 10x = 18

7x - 10x + 15 = 18

-3x + 15 = 18

Subtract 15 from both sides to eliminate 15 on the left

-3x + 15 - 15 = 18 - 15

-3x = 3

Divide both sides by by -3 to isolate x

-3x/-3 = 3/-3

x = -1
