A farmer looks out into the barnyard and sees the pigs and the chickens. "I count 70 heads and 180 feet, How many pigs and chickens are there?

Respuesta :

Answer:

Pigs = 20 and Chickens = 50

Step-by-step explanation:

Let the number of pigs be x

and let the number of chicken be y

Thus, x + y = 70

Since Chicken has 2 legs and pigs has 4 legs.

⇒ 4x + 2y = 180

Solving both equations,

We get, x = 20 and y = 50

Thus number of pigs = 20

and, number of chickens = 50.
