Answer 3

\[\large\rm \frac{1}{4z}=-\frac{7}{8}+\frac{1}{8z}\]This is our problem?

Answer 4

To make things easier on us, we would like to get rid of the denominators.
We can do that by multiplying both sides by the `Least Common Multiple` of our denominators.

Answer 5

Do you remember how to find LCM? :)
