5x-4=36
Square both sides of the equation.
5x-4-\left(-4\right)=36-\left(-4\right)
Add 4 to both sides of the equation.
5x=36-\left(-4\right)
Subtracting -4 from itself leaves 0.
5x=40
Subtract -4 from 36.
\frac{5x}{5}=\frac{40}{5}
Divide both sides by 5.
x=\frac{40}{5}
Dividing by 5 undoes the multiplication by 5.
x=8
Divide 40 by 5.
