Solve for z
z=\frac{36-x^{2}}{5}
Solve for x (complex solution)
x=-\sqrt{36-5z}
x=\sqrt{36-5z}
Solve for x
x=\sqrt{36-5z}
x=-\sqrt{36-5z}\text{, }z\leq \frac{36}{5}

5z=36-x^{2}
Subtract x^{2} from both sides.
\frac{5z}{5}=\frac{36-x^{2}}{5}
Divide both sides by 5.
z=\frac{36-x^{2}}{5}
Dividing by 5 undoes the multiplication by 5.
