Question

There are three chickens (large, medium, and small). They weighed themselves in different groupings. Below is the information we have: the large chicken plus the medium chicken weighs 10.6 kilograms; the large chicken plus the small chicken weighs 8.5 kilograms; the medium chicken and the small chicken weigh 6.1 kilograms. What is the weight of each chicken? Show how you figured it out.

Answer 1

L+M = 10.6

L+S = 8.5

S+M = 6.1

subtract 3rd from 2nd equation

L-M = 2.4

add to 1st equation

2L = 13

L = 6.5 kg weight for the Large Chicken

S= 2 kg weight for the Small Chicken

M = 4.1 kg weight for the Medium Chicken
