3\sqrt{x}+3-3=15-3
Subtract 3 from both sides of the equation.
3\sqrt{x}=15-3
Subtracting 3 from itself leaves 0.
3\sqrt{x}=12
Subtract 3 from 15.
\frac{3\sqrt{x}}{3}=\frac{12}{3}
Divide both sides by 3.
\sqrt{x}=\frac{12}{3}
Dividing by 3 undoes the multiplication by 3.
\sqrt{x}=4
Divide 12 by 3.
x=16
Square both sides of the equation.
