-8y+3=-5x^{2}
Subtract 5x^{2} from both sides. Anything subtracted from zero gives its negation.
-8y=-5x^{2}-3
Subtract 3 from both sides.
\frac{-8y}{-8}=\frac{-5x^{2}-3}{-8}
Divide both sides by -8.
y=\frac{-5x^{2}-3}{-8}
Dividing by -8 undoes the multiplication by -8.
y=\frac{5x^{2}+3}{8}
Divide -5x^{2}-3 by -8.
