4y+125=175-2x^{2}
Subtract 2x^{2} from both sides.
4y=175-2x^{2}-125
Subtract 125 from both sides.
4y=50-2x^{2}
Subtract 125 from 175 to get 50.
\frac{4y}{4}=\frac{50-2x^{2}}{4}
Divide both sides by 4.
y=\frac{50-2x^{2}}{4}
Dividing by 4 undoes the multiplication by 4.
y=\frac{25-x^{2}}{2}
Divide -2x^{2}+50 by 4.
