A farmer has both chickens and sheep on his farm. He has a total of 25 animals and there are 72 legs on his farm. How many of each animal is there?
(I think the answer is 18 (sheep) as chickens are birds not animals!!!

c = chickens
s = sheep
c+s = 25
2 c + 4 s = 72 or c + 2 s = 36
from first equation c = 25s
so
25  s + 2 s = 36
s = 11
then c = 14
