\sqrt{4x+8}+5-5=11-5
Subtract 5 from both sides of the equation.
\sqrt{4x+8}=11-5
Subtracting 5 from itself leaves 0.
\sqrt{4x+8}=6
Subtract 5 from 11.
4x+8=36
Square both sides of the equation.
4x+8-8=36-8
Subtract 8 from both sides of the equation.
4x=36-8
Subtracting 8 from itself leaves 0.
4x=28
Subtract 8 from 36.
\frac{4x}{4}=\frac{28}{4}
Divide both sides by 4.
x=\frac{28}{4}
Dividing by 4 undoes the multiplication by 4.
x=7
Divide 28 by 4.
