Katen [24]

First, let the number of skis rented by x and the number of snowboards rented by y. We can then assemble the first equation from the amount of money made from the rentals.


44x + 58y = 2232


The second equation can come from the fact that 9 more skis were rented than snowboards.


y = x - 9


Therefore our system is:


44x + 58y = 2232

y = x - 9
