Given that:
Original rating = 27
Total possible rating points = 30
Drop in rating point per month = 3

F(m) = original rating - drop in rating per month * number of months since release
F(m) = 27 - 3(m)
F(m) = 27 - 3m
You are trying to solve for y (get y by itself)
9y + 10 = -8 Subtract 10 on both sides
9y + 10 - 10 = -8 - 10
9y = -18 Divide 9 on both sides
y = -2
