    128 kids

    125 adults

    Step-by-step explanation:

    X = number of kids

    Y = number of adults

    1.5X + 4Y = 692

    X + Y = 253

    4X + 4Y = 1012

    (4X + 4Y = 1012) - (1.5X + 4Y = 692)

    (4X - 1.5X) + (4Y - 4Y) = 1012 - 692

    2.5X = 320

    X = 320/1.5

    X = 128 kids

    253 - 128 = 125 adults
