Question

There are 8 animals in the barn. Some are ducks and some are buffalo. There are 24 legs in all. How many of each animal are there? Show your work, please.

Answer 1

Answer: 4 buffalos and 20 chickens (i think)

Explanation:

2x+4y= 8

Ducks have 2 legs and buffalos have 4.

x= ducks y=buffalos

2(24-y)+4y=24

48-2y+4y=40

2y=8

y=4

4 buffalos

x+y=24

x=24-y

x=24-4

x=20

20 ducks
