    20 - (4x + 4) = 4x + 1 - 8x

    Pretend that there is a - 1 in front of the bracket

    20-1 (4x+4) = 4x+1-8x

    20-4x-4=4x+1-8x

    20-4-4x=4x-8x+1

    16-4x=-4x+1

    Move - 4x to the left side. Sign changes from - 4x to + 4x.

    Move + 16 to the other side. Sign changes from + 16 to - 16.

    16-16-4x+4x=-4x+4x+1-16

    0=-15

    X=1.875 because when you have a - 4 and a positive four you add the opposite and that will give you a positive 8x
