Afarmer looks out into the barnyard and sees the pigs and the chickens. he says to his daughter, "i count 153 heads and 346 feet. how many pigs and how many chickens are out there? "

There are 20 pigs and 133 chickens.

Step-by-step explanation:

We know that a pig has 4 legs and a chicken has 2 legs.

Let x be the number of pigs and y be the number of chickens , then we have the following system of linear equations:-

Multiply 2 on both sides of equation (1), we get

Eliminate equation (3) from equation (2), we get

Put x= 20 in (1), we get

Hence, there are 20 pigs and 133 chickens.

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
