3r-6=4
Square both sides of the equation.
3r-6-\left(-6\right)=4-\left(-6\right)
Add 6 to both sides of the equation.
3r=4-\left(-6\right)
Subtracting -6 from itself leaves 0.
3r=10
Subtract -6 from 4.
\frac{3r}{3}=\frac{10}{3}
Divide both sides by 3.
r=\frac{10}{3}
Dividing by 3 undoes the multiplication by 3.
