    X = ski rentals, y = snowboarding rentals

    x + y = 28 ... x = 28 - y

    16x + 19y = 478

    16 (28 - y) + 19y = 478

    448 - 16y + 19y = 478

    -16y + 19y = 478 - 448

    3y = 30

    y = 30/3

    y = 10

    x + y = 28

    x + 10 = 28

    x = 28 - 10

    x = 18

    so 18 rented skis and 10 rented snowboards
