1=(2A)/(1+A) Solve for A

Here's what I'm getting so far,

A=2/(1+A)

A(1+A)=2

Trial and error says A=1

Is there an algebraic way to solve this problem without resorting to trial and error? I know this one is a no brainier but I'd like a more definite method in case I come across some more complex problems in the future.
