    Division Property of Equality

    Step-by-step explanation:

    from the second from last step, we have

    2x = - 36

    if we divide both sides of the equation equally by 2, we get

    (2x) / 2 = (-36) / 2

    x = - 18 ..., which is exactly the last step that is given in the question

    hence in order to get to the last step, we divide both sides of the equality by 2 (a non-zero number).

    AKA "Division Property of Equality"
