Solve for y
y=\frac{x^{2}}{3}-\frac{81}{2}
Solve for x (complex solution)
x=-\frac{\sqrt{12y+486}}{2}
x=\frac{\sqrt{12y+486}}{2}
Solve for x
x=\frac{\sqrt{12y+486}}{2}
x=-\frac{\sqrt{12y+486}}{2}\text{, }y\geq -\frac{81}{2}

-12y=486-4x^{2}
Subtract 4x^{2} from both sides.
\frac{-12y}{-12}=\frac{486-4x^{2}}{-12}
Divide both sides by -12.
y=\frac{486-4x^{2}}{-12}
Dividing by -12 undoes the multiplication by -12.
y=\frac{x^{2}}{3}-\frac{81}{2}
Divide 486-4x^{2} by -12.
