Ответ:
The correct option is 4.
Step-by-step explanation:
Let the number of sheep be x and the number of chickens be y.
It is given that there are total 16 animals.
The number of chickens, y, is 4 less than the number of sheep, x.
Using (1) and (2), we get
Add 4 on both the sides.
Divide both sides by 2.
Put x=10 in equation (1).
Subtract 10 from both the sides.
The ordered pair (10,6) represents the number of chickens and sheep. Therefore the correct option is 4.
