\sqrt{3x}+3=5\times 3
Multiply both sides by 3.
\sqrt{3x}+3=15
Multiply 5 and 3 to get 15.
\sqrt{3x}=15-3
Subtract 3 from both sides.
\sqrt{3x}=12
Subtract 3 from 15 to get 12.
3x=144
Square both sides of the equation.
\frac{3x}{3}=\frac{144}{3}
Divide both sides by 3.
x=\frac{144}{3}
Dividing by 3 undoes the multiplication by 3.
x=48
Divide 144 by 3.
