Solve for y
y=-\frac{x^{2}}{2}+\frac{13}{4}
Solve for x (complex solution)
x=-\frac{\sqrt{26-8y}}{2}
x=\frac{\sqrt{26-8y}}{2}
Solve for x
x=\frac{\sqrt{26-8y}}{2}
x=-\frac{\sqrt{26-8y}}{2}\text{, }y\leq \frac{13}{4}

8y=26-4x^{2}
Subtract 4x^{2} from both sides.
\frac{8y}{8}=\frac{26-4x^{2}}{8}
Divide both sides by 8.
y=\frac{26-4x^{2}}{8}
Dividing by 8 undoes the multiplication by 8.
y=-\frac{x^{2}}{2}+\frac{13}{4}
Divide 26-4x^{2} by 8.
