2\sqrt{x}-12-\left(-12\right)=8-\left(-12\right)
Add 12 to both sides of the equation.
2\sqrt{x}=8-\left(-12\right)
Subtracting -12 from itself leaves 0.
2\sqrt{x}=20
Subtract -12 from 8.
\frac{2\sqrt{x}}{2}=\frac{20}{2}
Divide both sides by 2.
\sqrt{x}=\frac{20}{2}
Dividing by 2 undoes the multiplication by 2.
\sqrt{x}=10
Divide 20 by 2.
x=100
Square both sides of the equation.
