Farm Animal Counting and Equations

The video tutorial explains how to solve a problem involving counting chickens and pigs in a field. The farmer counts 90 heads and 286 legs, and the task is to determine the number of chickens and pigs. The tutorial sets up a system of equations using variables for chickens and pigs, then solves the equations using substitution. The solution is verified by checking the total number of heads and legs, confirming the farmer saw 37 chickens and 53 pigs.

What is the total number of heads counted by the farmer?

• 37

• 53

• 286

What equation represents the total number of heads?

• 2C + 4P = 286

• C + P = 90

• 2C - 4P = 286

• C - P = 90
