Solve for y
y=\frac{5x^{2}-8}{7}
Solve for x (complex solution)
x=-\frac{\sqrt{35y+40}}{5}
x=\frac{\sqrt{35y+40}}{5}
Solve for x
x=\frac{\sqrt{35y+40}}{5}
x=-\frac{\sqrt{35y+40}}{5}\text{, }y\geq -\frac{8}{7}

5x^{2}-3y-4y=8
Subtract 4y from both sides.
5x^{2}-7y=8
Combine -3y and -4y to get -7y.
-7y=8-5x^{2}
Subtract 5x^{2} from both sides.
\frac{-7y}{-7}=\frac{8-5x^{2}}{-7}
Divide both sides by -7.
y=\frac{8-5x^{2}}{-7}
Dividing by -7 undoes the multiplication by -7.
y=\frac{5x^{2}-8}{7}
Divide 8-5x^{2} by -7.
