\frac{-27}{-9}=\sqrt{3x+9}
Divide both sides by -9.
3=\sqrt{3x+9}
Divide -27 by -9 to get 3.
\sqrt{3x+9}=3
Swap sides so that all variable terms are on the left hand side.
3x+9=9
Square both sides of the equation.
3x+9-9=9-9
Subtract 9 from both sides of the equation.
3x=9-9
Subtracting 9 from itself leaves 0.
3x=0
Subtract 9 from 9.
\frac{3x}{3}=\frac{0}{3}
Divide both sides by 3.
x=\frac{0}{3}
Dividing by 3 undoes the multiplication by 3.
x=0
Divide 0 by 3.
