h=height of ostrich
k=height of kiwi
h is 20 more than 4 times k
k=20+4k

k=108
108=20+4k
minus 20 from both sides
88=4k
divide both sides by 4
22=k

answer is A

Let the height of the kiwi be x, then the height of the ostrich is 20 + 4x.
20 + 4x = 108
4x = 108 - 20 = 88
x = 88/4 = 22
The height of the kiwi is 22 inches.
