I'm taking a differential equations college course, and I'm embarrassed to say that I'm a bit hung up on some algebra with a particular problem. I'm having issues getting an implicit solution into explicit form by hand. 

$\frac{y-2}{y+2}=\pm ce^{4x}$

My algebra skills are extremely rusty, and I'm banging my head against the wall trying to figure out how to solve this equation explicitly for $y$. I can get a solution on my calculator, but I would prefer to understand how to come to the solution by hand. Any help would be appreciated.
