Huixian's grandparents own a farm with m goats and n chickens. She counted that the animals have a
total of 52 heads and 140 legs. How many goats and
how many chickens are there on the farm?
Hint: A goat has 4 legs and a chicken has 2 legs.​

Step-by-step explanation:

2(heads) + 2(goats) = 140

Heads are given, so we get:

2(52) + 2(goats) = 140

104 + 2(goats) = 140

2(goats) = 36

goats = 18

Since we know the number of goats, we know the number of chickens.

34Chickens and 18 goats.
