7x-8=4
Square both sides of the equation.
7x-8-\left(-8\right)=4-\left(-8\right)
Add 8 to both sides of the equation.
7x=4-\left(-8\right)
Subtracting -8 from itself leaves 0.
7x=12
Subtract -8 from 4.
\frac{7x}{7}=\frac{12}{7}
Divide both sides by 7.
x=\frac{12}{7}
Dividing by 7 undoes the multiplication by 7.
