-3x-8=4
Square both sides of the equation.
-3x-8-\left(-8\right)=4-\left(-8\right)
Add 8 to both sides of the equation.
-3x=4-\left(-8\right)
Subtracting -8 from itself leaves 0.
-3x=12
Subtract -8 from 4.
\frac{-3x}{-3}=\frac{12}{-3}
Divide both sides by -3.
x=\frac{12}{-3}
Dividing by -3 undoes the multiplication by -3.
x=-4
Divide 12 by -3.
