Question

u=vw +z for x

Answer 1

There is no x in the equation.

Answer 2

I meant v lol sorry haha

Answer 3

Remember, the goal is to isolate v, so you will can use all sorts of operations to achieve that goal. Subtract z from both sides, you have u-z=vw. Now we multiply both sides by 1/w we finally get v=u-z/w.
