On average, an okapi weighs 290 kilograms and a llama weighs 160 kilograms.

O=Okapi
L=llama

O+L=450
3L=O+190

Solving that setup equation gets us with

4L=640

Divided by 4 to get each llama weighing 160KG

160+O=450

450-160=290

Getting the okapi to weigh 290KG

Hope this helped! Have a great day!!
