Answer 1

Answer:

Step-by-step explanation:

let x be the number of legs and y be the number oh heads, then

x = 14 + 2y

4*sheep + 2*hens =

= 14 + 2*sheep + 2*hens

2*sheep = 14

sheep = 7.

thus the number of sheep is 7.

Answer 2

Answer:

Step-by-step explanation:

Let the number of cows be X and the number of hens be Y.

Then,

4x + 2y = 2 (x + y) + 14

(since horses have 4 legs and hens have only 2 legs).

4x + 2y = 2x + 2y + 14

2x = 14

x = 7.

Hence, the number of sheep is 7.
