√2=1+-------
          2 +  1         Solve for x (exact value)
              ------
               2+x

I've run out of things to try with this, probably something simple I'm just missing but I can get to a point and then I just can't get x on it's own. Any help appreiciated

Hmm, didn't quite come out right it's spose to be 1÷(2+(1÷(2+x)))+1=√2 (The 1 at top of original post spose to be over the --------)
