    Let us say that:

    x = weight of llamas

    y = weight of okapi

    From the problem, we can create the equations:

    x + y = 450 - - > 1

    3 x = y + 190 - - > 2

    Rewriting equation 1:

    x = 450 - y

    From equation 2:

    3 (450 - y) = y + 190

    1350 - 3 y = y + 190

    4 y = 1160

    y = 290

    From equation 1:

    x = 450 - 290

    x = 160

    Therefore a llama weighs 160 kilograms while okapi weigh 290 kilograms on average.
