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.
50 horses and 10 chickens
Let the number of chickens be x and the number of pigs be y. Each chicken has 1 head and 2 feet, while each pig has 1 head and 4 feet. We can then write the equations x + y = 48 (counting heads) and 2x + 4y = 124 (counting feet). Solving these equations simultaneously gives x = 24 and y = 24, so there were 24 chickens and 24 pigs.
If all were horses there would be 428 legs. The shortfall of 36 legs represents 18 chickens so there are 89 horses.
7 cows and 11 chickens. Cows have 4 legs. Chickens have 2 legs. (4 legs)(7 cows) + (2 legs)(11 chickens) = 50 legs. 7 cow heads = 11 chicken heads = 18 heads.
Do-it-in-your-head method: If all animals were chickens there would be 90 legs. There are 20 extra legs, each on a cow, so there are 20 cows and therefore 25 chickens.
