    x = - 1

    Step-by-step 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
