Very quick algebraic manipulation help

  1. Sep 6, 2009 #1
    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:

    [tex]\frac{X+Y}{X-Y}[/tex]*[tex]Z_{0}[/tex] = [tex]Z_{L}[/tex]

    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.
