Select the two equations that will help you to solve this problem: The combined average weight of an okapi and a llama is 450 kilograms.

3 llamas, on average, weigh 190 kilograms more than an average okapi.

You want to find the average weight of each type of animal.

An average Ilama weighs 160 kilograms and an average okapi weighs 290 kilograms.

Step-by-step explanation:

Let,

x be the average weight of a Ilamas

y be the average weight of an okapi

According to given statement;

x + y = 450     Eqn 1

3x = y + 190   Eqn 2

From Eqn 2

y = 3x - 190     Eqn 3

Putting this value of y in Eqn 1

x + (3x-190) = 450

x + 3x - 190 = 450

4x = 450 + 190

4x = 640

Dividing both sides by 4

Putting x = 160 in Eqn 3

y = 3(160) - 190

y = 480 - 190

y = 290

Hence,

An average Ilama weighs 160 kilograms and an average okapi weighs 290 kilograms.
