    Right side

    Step-by-step explanation:

    3x - 8 = 4 (x + 5)

    3x - 8 = 4x + 20

    3x - 4x = 20 + 8

    -x = 28 (divide both sides by - 1)

    x = - 28

    x=-36

    Step-by-step explanation:

    I would start by distributing the right side first

    4 (x+5) is 4x+20.

    That gives you 3x-8=4x+20

    4x-3x=1x

    -28-8 = - 36

    x=-36
