3\sqrt{x}+2-2=7-2
Subtract 2 from both sides of the equation.
3\sqrt{x}=7-2
Subtracting 2 from itself leaves 0.
3\sqrt{x}=5
Subtract 2 from 7.
\frac{3\sqrt{x}}{3}=\frac{5}{3}
Divide both sides by 3.
\sqrt{x}=\frac{5}{3}
Dividing by 3 undoes the multiplication by 3.
x=\frac{25}{9}
Square both sides of the equation.
