if in a farm there is chickens and rabitts and the farmer counted 72 heads and 200 feet

Question

in a farm there are 72 heads and 200 feet .how many chickens and rabbits are in the farms?

 

Answer 1

This math word problem could be written as a system of 2 linear equations with two unknown variables R and C (which stand for rabbits and chickens, correspondingly):

 

R + C =72 (total rabbits and chickens)

4R + 2C = 200 (total legs)

 

Solving the system of equation:

 

R = 28 (rabbits)

C = 44 (chickens)
