    5x + 9 = x - 23

    move x to the other side

    sign changes from + x to - x

    5x-x+9 = x-x-23 (combine like terms)

    5x-x+9 = - 23

    4x+9 = - 23

    move - 9 to the other side

    4x+9-9 = - 23-9

    4x = - 23-9

    4x = - 32

    divide both sides by 4 to get x by itself

    4x/4 = - 32/4

    answer:

    x = - 8
