Accepted Solution
A:
x = surf boards, y = paddle boards
x + y = 44......x = 44 - y 45x + 60y = 2265
45(44 - y) + 60y = 2265 1980 - 45y + 60y = 2265 -45y + 60y = 2265 - 1980 15y = 285 y = 285/15 y = 19 <=== there were 19 paddle boards rented
x + y = 44 x + 19 = 44 x = 44 - 19 x = 25......and 25 surf boards rented
