Question
Okay, I'm in a calculus class but stuck on some algebra...it's not crucial that I get the answer to this but I'm wracking my brain because I can't remember how the following is obtained; if you can show me how this is done in steps I'd greatly appreciate it (I highly suspect it's something simple):
y / (1 - y) = x
solving for y is (I don't know what is being done in between to solve for y):
y = x / (1 + x)
I don't know why I'm having such a hard time with this, thanks for your help in advance.

y / (1 - y) = x
As usual, clear the fraction by multiplying by the denominator:
y = x(1-y)
Now expand to remove parentheses:
y = x - xy
Now collect the y's on one side:
y+xy = x
Factor out the y:
y(1+x) = x
I think you can probably make it from here, no?
