y=5, x=7 because if 3x5=15 then 15-7=8 dont report me if i do get this wrong
-1, -1 I think is the answer
The idea of using 4 because it's a factor is the wrong choice. If the equation were 5x = 88 and you divide by 4, you aren't getting a single 1x alone. So the "divide because it's a factor" choice is wrong.
