2x+4=36
Square both sides of the equation.
2x+4-4=36-4
Subtract 4 from both sides of the equation.
2x=36-4
Subtracting 4 from itself leaves 0.
2x=32
Subtract 4 from 36.
\frac{2x}{2}=\frac{32}{2}
Divide both sides by 2.
x=\frac{32}{2}
Dividing by 2 undoes the multiplication by 2.
x=16
Divide 32 by 2.
