Farmer John has goats and chickens on his farm. The total number of 4 legged goats and 2 legged chickens is 18. His son, Joseph counted 56 animal legs on the farm. Represent this situation with a system of linear equations and find the number of goats and chickens on the farm.

Answer :

Answer:

There are 10(4-legged) goats and 8(2-legged) chickens.

Step-by-step explanation:

  • Let x represent the number of 4 legged goats.
  • Let y represent the number of 2 legged chickens.

The total number of 4 legged goats and 2 legged chickens is 18.

Therefore: x+y=18

His son, Joseph counted 56 animal legs on the farm.

  • The number of legs by x (4 legged) goats = 4x
  • The number of legs by y (2 legged) Chickens = 2y

Therefore: 4x+2y=56

Solving the two equations simultaneously

x+y=18

4x+2y=56

From the first equation, x=18-y

Substitute x=18-y into the second equation

4x+2y=56

4(18-y)+2y=56

72-4y+2y=56

72-56=4y-2y

16=2y

y=8

Recall: x=18-y

           x=18-8=10

x=10, y=8

There are 10(4-legged) goats and 8(2-legged) chickens.

The number of goats and chickens on the farm is 10 and 8.

Linear system

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

The total number of 4 legged goats and 2 legged chickens is 18. His son, Joseph counted 56 animal legs on the farm.

Find the number of goats and chickens on the farm.

Let x be the goat and y be the hen.

The total number of 4 legged goats and 2 legged chickens is 18. then the equation will be

x + y = 18.....1

Joseph counted 56 animal legs on the farm. then the equation will be

4x +2y = 56.....2

On solving equations 1 and 2, we get

x = 10, and y = 8

Thus the number of goats and chickens on the farm are 10 and 8.
