A local animal shelter had four more than six times as many adult cats as kittens. After eight of the kittens were adopted, the shelter had four fewer than eight times as many adult cats as kittens. How many adult cats are at the shelter?

• Math -

kittens --- x

kittens = x-8

6x+4 = 8(x-8) - 4
6x + 4 = 8x - 64 - 4
-2x = -72
x = 36

Number of adults has not changed, so there are
6(36) + 4 or 220 adult cats

check:
originally..
number of kittens 36
cats = 220
is 6(36) + 4 = 220 ? yes

kittens = 28
is 8(28)-4 = 220 ? YES
