Are you saying ?

If so, to find x you need to do various things to both sides of the equation. A good first step would be to multiply both sides by qz:

Can you see where to go from there? For starters you can cancel out the qz/qz on the right, to get

Then you just need to do a bit of division to get rid of the bits around x and q.
3. what if you want to find Q is it the same method

4. To get x on its own, divide both sides by w, or to get q, divide both sides by (z*Y). Easy.
