Which of the following values is the solution to the equation w/-7 = - 21?

147

-147

3

-3

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

-147

-147/7 = 21
