    Step-by-step explanation:

    We want to know what the value of w is, so we want to get it by itself. So we start by multiplying - 7 to both sides of the equation.

    -7 W

    ___ x ___ = - 21 x - 7

    1 - 7

    By cross cancelling both - 7s you get 1w on the left side and 147 on the right

    1w = 147

    1w is the same as w so your answer is

    W = 147
