Question

a farm has only chickens and cows on it for a total of 145 animals l. however there are only 324 animal legs. write a system of equations that models this.

Answer 1

Explanation:

x = chickens and y = cows

chickens and cows ....for a total of 145

x + y = 145

324 animal legs....chicken(x) has 2 legs, cow(y) has 4 legs

2x + 4y = 324
