r = -31
Step-by-step explanation:
The picture is how I solved it.
20 + 17y = -6 + 15y
First, regroup your terms.
Second, take away '15y' from each side.
Third, subtract '17y - 15y' to get '2y'.
Fourth, take away '20' from both sides.
Fifth, simplify '-6 - 20' to get '-26'.
Sixth, divide both sides by '2'.
