There are 50 donkeys and chickens on a farm. There are a total of 174 legs. Create a system of equations to figure out how many of each animal the farm has

Answer 1

4D + 2C = 174

D+ C = 50

double the 2nd equation to get

2D + 2C = 100

subtract from the 1st equation to get

2D = 74

D = 74/2 = 37 donkeys

C = 50-37 = 13 chickens

4(37) + 2(13) = 148 + 26 = 174 legs
