Question

there are a total of 44 goats and chickens being raised. between them, they have 134 legs. how many goats are in total? how many chickens in total?

Answer 1

21 chickens and  23 goats=44

21x2=42    23x4=92

42+92 = 134 legs

x=goats     y= chikens     goats 4 legs   chickens 2 legs

x+y=44      x=44-y

4(44-y) + 2(y) =134

176-4y +2y = 134

176-2y=134

-2y= -42

-y= -21

y=21
