85 chickens
There are 42 chickens in the farm.
there are 36 horses and 23 chickens.........
Suppose there are x chickens and y cows Then heads => x + y = 64 And Legs => 2x + 3y = 147 2*Heads: 2x +2y = 128 Subtract from Legs: 19 = y Substitute in Heads: x = 45 Answer: 45 chickens.
There are four animals in total if you have three goats and a cow.

9 sheeps and 18 chickens
Assuming that all of the animals are "normal" (no amputees, 2-headed mutations, etc.) : 15 cows (15 x 4 = 60 legs) plus 5 chickens (5 x 2 = 10 legs) gives a total of 20 heads and 70 legs.
Suppose there are x chickens and y cows Then heads => x + y = 64 And Legs => 2x + 3y = 147 2*Heads: 2x +2y = 128 Subtract from Legs: 19 = y Substitute in Heads: x = 45 Answer: 45 chickens.
35 pigs, 65 chickens
Do-it-in-your-head method: If all animals were chickens there would be 96 legs. There are 26 extra legs, each on a cow, so there are 26 cows and therefore 22 chickens.
There are 61 horses and 10 chickens on the farm.
