Why can't I divide 2 to the other side in y+1=2square root/y+1? I would like to get rid of the square root in y+1 by squaring it, but my answer sheet say I can't divide the 2 out but I just have to square it with the SR/y+1 to get y.

Original problem: sr/2y+3-sr/y+1=1

I don't know where to find the symbol for square root so I say "sr/"
