Solve for y
y=\frac{x^{2}-16}{3}
Solve for x (complex solution)
x=-\sqrt{3y+16}
x=\sqrt{3y+16}
Solve for x
x=\sqrt{3y+16}
x=-\sqrt{3y+16}\text{, }y\geq -\frac{16}{3}

-3y=16-x^{2}
Subtract x^{2} from both sides.
\frac{-3y}{-3}=\frac{16-x^{2}}{-3}
Divide both sides by -3.
y=\frac{16-x^{2}}{-3}
Dividing by -3 undoes the multiplication by -3.
y=\frac{x^{2}-16}{3}
Divide -x^{2}+16 by -3.
