Ducks have 1 head, 2 feet.
Cows have 1 head, 4 feet.
That means there are 1414 animals in total.
Now let's make an equation.
1414 = 2x + 4x
1414 = total animals
2x = duck feet
4x = cow feet
2x and 4x = feet #
and let's solve that equation
1414 = 2x + 4x
1414 = 6x
/6 /6
235 = x
(apx.)
Ducks = 2x = 2(235) = 470
Cows = 4x = 4(235) = 940
940 + 470 = 1410.
Since there is a remainder of 4, it can be said that 1 animal with 4 legs will complete this (1414). However, it can also be said that 2 animals with 2 legs will complete this too. So.
Combination 1:
Cows = 941
Chickens = 470
Combination 2:
Cows = 940
Chickens = 472
