(2.5 + 2x) / (2.0 - x) = 2.50

and X = 0.56 (sorry, I wasn't sure how to use latex)

My question is this - how do you do the actual calculations, step by step? I'm not even sure what to call this problem to search for it on the internet. I need to know how to manipulate these though, so I may as well become familiar with them.

Any help or links to good sites would be greatly appreciated!
