    8-x=x+3 (4-x) - x

    8-x=x+12-3x-x

    8-x=x+12-4x

    8-x=-3x+12

    -x=-3x+4

    2x=4

    x=2

    x - 12 (8-x) = x + 3 (4-x) - x

    x + (-12) (8) + (-12) (-x) = x + (3) (4) + (3) (-x) + - x

    x + - 96 + 12x = x+12 + - 3x + - x

    (x + 12x) + (-96) = (x + - 3x + - x) + (12)

    13x + - 96 = - 3x + 12

    13x - 96 = - 3x + 12

    13x - 96 + 3x = - 3x + 12 + 3 x

    16x - 96 = 12

    16x - 96 + 96 = 12 + 96

    16x = 108

    16x / 16 = 108/16

    x=27/4

    Answer is x=27/4
