\frac{3\sqrt{x+2}}{3}=\frac{12}{3}
Divide both sides by 3.
\sqrt{x+2}=\frac{12}{3}
Dividing by 3 undoes the multiplication by 3.
\sqrt{x+2}=4
Divide 12 by 3.
x+2=16
Square both sides of the equation.
x+2-2=16-2
Subtract 2 from both sides of the equation.
x=16-2
Subtracting 2 from itself leaves 0.
x=14
Subtract 2 from 16.
