5\sqrt{x}+4-4=12-4
Subtract 4 from both sides of the equation.
5\sqrt{x}=12-4
Subtracting 4 from itself leaves 0.
5\sqrt{x}=8
Subtract 4 from 12.
\frac{5\sqrt{x}}{5}=\frac{8}{5}
Divide both sides by 5.
\sqrt{x}=\frac{8}{5}
Dividing by 5 undoes the multiplication by 5.
x=\frac{64}{25}
Square both sides of the equation.
