Solve for x
x=\frac{y^{2}-25}{5}
Solve for y (complex solution)
y=-\sqrt{5\left(x+5\right)}
y=\sqrt{5\left(x+5\right)}
Solve for y
y=\sqrt{5\left(x+5\right)}
y=-\sqrt{5\left(x+5\right)}\text{, }x\geq -5

5x+25=y^{2}
Swap sides so that all variable terms are on the left hand side.
5x=y^{2}-25
Subtract 25 from both sides.
\frac{5x}{5}=\frac{y^{2}-25}{5}
Divide both sides by 5.
x=\frac{y^{2}-25}{5}
Dividing by 5 undoes the multiplication by 5.
x=\frac{y^{2}}{5}-5
Divide y^{2}-25 by 5.
