Answer 6

Oh, you need to solve for \(d_1\)

Well, you are given \(f_1d_1 = f_2d_2\) and you need to isolate \(d_1\), so we need to do something about \(f_1\); get it to other side.

Any idea how to do that?

Answer 7

Do you know algebra? All you need to do is to get f_1 to other side of the equation.
