\sqrt{x-5}+2-2=6-2
Subtract 2 from both sides of the equation.
\sqrt{x-5}=6-2
Subtracting 2 from itself leaves 0.
\sqrt{x-5}=4
Subtract 2 from 6.
x-5=16
Square both sides of the equation.
x-5-\left(-5\right)=16-\left(-5\right)
Add 5 to both sides of the equation.
x=16-\left(-5\right)
Subtracting -5 from itself leaves 0.
x=21
Subtract -5 from 16.
