4r%2B12%2B3r=3%284-r%29 Start with the given equation.


4r%2B12%2B3r=12-3r Distribute.


7r%2B12=12-3r Combine like terms on the left side.


7r=12-3r-12 Subtract 12 from both sides.


7r%2B3r=12-12 Add 3r to both sides.


10r=12-12 Combine like terms on the left side.


10r=0 Combine like terms on the right side.


r=%280%29%2F%2810%29 Divide both sides by 10 to isolate r.


r=0 Reduce.
