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.
Add 7 to both sides.
13+7=
20
Answer:

Explanation:
Here, we want to find the bigger solution
We can start by factoring x as follows:

The bigger solution is x= 11
Answer:
1. (x + 2)2 = x + 2 x 2 = 4x HOP THAT HELPS.
