A farmer who keeps goats and chickens boasted to another:
I have animals in the yard with 120 legs and only 37 heads. How many goats and how many chickens did he have?
its urgent

Respuesta :

Answer:

Step-by-step explanation:

chickens x

goats y

4x+ 2y=120           2y=120-4x/ 2        y= 60- 2x

x+y= 37                  x+y=37                x+ 60- 2x= 37

 

y= 60-2x

x= 23

y= 60 - 2*23            y= 14

x= 23                        x=23
