Very quick algebraic manipulation help

[dalarev]

1. The problem statement, all variables and given/known data

x and y are actually variables for another problem I have, but that doesn't matter. Given:

\frac{X+Y}{X-Y}*Z_{0} = Z_{L}


3. The attempt at a solution

I'm trying to solve for Y here. I have the answer, it's part of my notes, but I can't work out the algebra to derive it.

Hi dalarev! :wink:

Just multiply both sides by (X - Y), and then put all the Y terms on one side, and all the other terms on the other side. :smile:

Doh! :facepalm:

I tried to do it in my head and forgot the expand the factors I get on each side. Geez..


Thanks for the quick response, /thread.
