First gather the terms containing z on one side and the ones that don't on the other. Then rewrite the surds and multiples of sqrt2 and take a factor of z out and rearrange to make z the subject.
3. Take your Zs to one side, and your numbers to the other. Factorize out your Zs on the Z side (so you get Z*(something-something)) then you can figure out the surds in the bracket and then solve it like any other linear equation.

That's right now divide through by sqrt2, remembering that 6=3x2 and 2/sqrt2=sqrt2.
6. I got the answer as 6/root 2, which works.
