Need some help!
Aaron and Wayne have made 181 and 3093 cards respectively. Everyday, Aaron makes 39 more while Wayne makes 7. How many days will it take for both to have the same number of cards?

3093-181=2912
39-7=32

N - Number of days
Aaron: 181 + 39N
Wayne: 3093 + 7N
181+39N=3093+7N
32N=2912
N=91
Number of days to take for both to have the same number of cards = 91
