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