A Farm raises pigs and chickens. The farmer has a total of 66 animals. One Day he Counts the legs of all his animals and realize he has a total of 174 legs. How many chickens does the Farmer have?

Pigs = 21

Chicken = 45

Step-by-step explanation:

Let the pigs be represented by p

Let the chicken be represented by c.

From the question,

p + c = 66

4p + 2c = 174

4 × ( p + c = 66)

1 × (4p + 2c = 174)

4p + 4c = 264

- 4p + 2c = 174

2c = 90

c = 90/2 = 45

There are 45 chickens

Simce the farmer has a total of 66 animals, the number of pigs will be:

= 66 - 45

= 21 pigs
