    4*8x is 32x

    4*-2 is - 8

    32x-8=72

    Move eight to the other side as a positive number

    32x=80

    Divide both sides by 32

    Therefore x is equal to 2.5

    Answer:-2

    Step-by-step explanation:

    4 (8x - 2) = -72

    Divide both sides by 4

    4 (8x - 2) ➗ 4=-72 ➗ 4

    8x-2=-18

    add 2 to both sides

    8x-2+2=-18+2

    8x=-16

    Divide both sides by 8

    8x ➗ 8=-16 ➗ 8

    x=-2
