Answers matching "The combined average weight of an okapi and a llama is 450 kilograms. The average weight of 3 llamas is 190 kilograms more than the average weight of one okapi. On average, how much does an okapi weigh, and how much does a llama weigh?"

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.
