First, you have to be clear on what "answer" means. The 'answer' is the number

that 'f' must be, otherwise the statement isn't true.

For example, 'f' can't be '1'. If 'f' is '1', then -28 = -7, and that's not true.

There's only one number that 'f' can be. Here's how to find it:

-28 = -7 f

Divide each side of the equation by -7 :

4 = f
