  1. Step one: combine like-term - put all the x on one side and all the whole number on the other side by addition/subtraction.

    Step two: get x on one side by division/multiplication.

    Ex:
    3x+5=2x-3
    Subtract 2x and -5 on each side of the equation
    3x-2x + 5-5 = 2x-2x - 3-5
    x = -8
