Solve for x
x=\frac{y^{2}}{40}
Solve for y (complex solution)
y=-2\sqrt{10x}
y=2\sqrt{10x}
Solve for y
y=2\sqrt{10x}
y=-2\sqrt{10x}\text{, }x\geq 0

40x=y^{2}
Swap sides so that all variable terms are on the left hand side.
\frac{40x}{40}=\frac{y^{2}}{40}
Divide both sides by 40.
x=\frac{y^{2}}{40}
Dividing by 40 undoes the multiplication by 40.
