I searched, to no avail, however my time is limited.

I have the equation:

x = (1+e^y) / (1-e^y)

and I need to solve for y. Using the TI, I get the solution as:

y = ln( (x-1) / (x+1) )

But I need to know how to do it by hand. I took Calculus 1 so long ago, I just simply forgot the steps. Any assistance would be much appreciated.

Thanks!
