x=5\sqrt{y}
Combine \sqrt{y} and 4\sqrt{y} to get 5\sqrt{y}.
5\sqrt{y}=x
Swap sides so that all variable terms are on the left hand side.
\frac{5\sqrt{y}}{5}=\frac{x}{5}
Divide both sides by 5.
\sqrt{y}=\frac{x}{5}
Dividing by 5 undoes the multiplication by 5.
y=\frac{x^{2}}{25}
Square both sides of the equation.
