2\sqrt{x}-8-\left(-8\right)=-\left(-8\right)
Add 8 to both sides of the equation.
2\sqrt{x}=-\left(-8\right)
Subtracting -8 from itself leaves 0.
2\sqrt{x}=8
Subtract -8 from 0.
\frac{2\sqrt{x}}{2}=\frac{8}{2}
Divide both sides by 2.
\sqrt{x}=\frac{8}{2}
Dividing by 2 undoes the multiplication by 2.
\sqrt{x}=4
Divide 8 by 2.
x=16
Square both sides of the equation.
