You would cross-multiply the two fractions to just be left with 1 fraction on the LHS. Then multiply both sides by the denominator of this fraction and rearrange to get a quadratic equal to 0. From there, I'm assuming you know what to do :smile:

"Cross Multiply" is a term usually used for the situation where you have a single fraction = a single fraction. e.g.

\frac{a}{b}=\frac{c}{d}\; \Rightarrow ad=bc

In this case you have a fraction on the left + another fraction = a number and the algebra looks like this

\frac{a}{b}+\frac{c}{d}=e \;\Rightarrow \frac{ad+bc}{bd}=e

and then you are in the single fraction either side situation giving us

ad+bc=bde
