Solve for y
y=-\frac{x^{3}}{2}+4
Solve for x (complex solution)
x=e^{\frac{2i\pi }{3}}\sqrt[3]{8-2y}
x=\sqrt[3]{8-2y}
x=e^{\frac{4i\pi }{3}}\sqrt[3]{8-2y}
Solve for x
x=\sqrt[3]{8-2y}

2y=8-x^{3}
Subtract x^{3} from both sides.
\frac{2y}{2}=\frac{8-x^{3}}{2}
Divide both sides by 2.
y=\frac{8-x^{3}}{2}
Dividing by 2 undoes the multiplication by 2.
y=-\frac{x^{3}}{2}+4
Divide -x^{3}+8 by 2.
