Solve for y
y=-\frac{x^{2}}{2}+\frac{25}{4}
Solve for x (complex solution)
x=-\frac{\sqrt{50-8y}}{2}
x=\frac{\sqrt{50-8y}}{2}
Solve for x
x=\frac{\sqrt{50-8y}}{2}
x=-\frac{\sqrt{50-8y}}{2}\text{, }y\leq \frac{25}{4}

4y=25-2x^{2}
Subtract 2x^{2} from both sides.
\frac{4y}{4}=\frac{25-2x^{2}}{4}
Divide both sides by 4.
y=\frac{25-2x^{2}}{4}
Dividing by 4 undoes the multiplication by 4.
y=-\frac{x^{2}}{2}+\frac{25}{4}
Divide 25-2x^{2} by 4.
