Not possible

Explanation:

For each variable you want to solve for, a separate equation is needed. For example, if you want to solve for x in x=5⋅2, you only need one equation. If you wanted x and y, you would need a system of two equations. If you wanted three variables, you need three equations, so on and so forth.

Use distributive property on the right-hand side and isolate z.

Explanation:

First we can use the distributive property to take out the z on the right-hand side:
y2−4x=z(8−3y)

To isolate the z, we can divide over the 8−3y:
z=y2−4x8−3y, where y≠83 which gives us the expression for z
