Easy problem... frustrated!
While trying to determine the inverse of (1) y = (12x) / (1+x), replace x with y and viceversa.
(2) This gives x = (12y) / (1+y) The goal is to isolate y in (2), a simple task... however I seem to have forgotten how to do such simple isolations. This part of the problem was skipped in my solutions manual. The final answer is y = (1x) / (2+x) How would one go about solving for y from the original equation? Thank you for your time.

Start
Multiply to both sides Add and subtract to both sides Factor out Divide to both sides
