There are 20 animals in the barn. Some are geese and some are buffalo. There are 64 legs in all. How many of each animal are there?

20 animals = x chickens (2 legs)  + y horses (4 legs).

x+y=20 (total number of animals)

2x+4y=64 *total number of legs)

x+y=20

x+2y=32

If you solve this system of animal with 2 and 4 legs, you get 6 chickens and 14 horses

x=6

y=14
