Solve for y
y=\frac{x^{2}}{20}
Solve for x (complex solution)
x=-2\sqrt{5y}
x=2\sqrt{5y}
Solve for x
x=2\sqrt{5y}

20y=x^{2}
Swap sides so that all variable terms are on the left hand side.
\frac{20y}{20}=\frac{x^{2}}{20}
Divide both sides by 20.
y=\frac{x^{2}}{20}
Dividing by 20 undoes the multiplication by 20.
