Once upon a time, there was a former whose family raised pigs and chickens. One morning, the farmer's wife looked into the barny
Fed [463]

Using a system of equations, it is found that:

  • There are 8 chickens in the yard.
  • There are 16 pigs in the yard.

-----------------------------------------

This question is solved using a system of equations. I am going to say that:

  • x is the number of chickens.
  • y is the number of pigs.

-----------------------------------------

  • A chicken has 1 head, as do a pig.
  • There are 24 heads.

Thus:

x + y = 24 \rightarrow y = 24 - x

-----------------------------------------

  • A chicken has 2 feet.
  • A pig has 4 feet.
  • In total, there are 80 feet.

Thus:

2x + 4y = 80

-----------------------------------------

Number of chicken:

Since y = 24 - x

2x + 4y = 80

2x + 4(24 - x) = 80

2x + 96 - 4x = 80

2x = 16

x = \frac{16}{2}

x = 8

There are 8 chickens in the yard.

-----------------------------------------

Number of pigs:

y = 24 - x = 24 - 8 = 16

There are 16 pigs in the yard.
