step-by-step explanation:

Good evening ,

8 chickens8 horsesStep-by-step explanation:

let c = the number of chickens

let h = the number of horses

You have to solve this system

h + c = 16

4h + 2c = 48

h + c = 16 ⇒ h = 16 - c

If we substitute h=16-c in the second equation we will get :

4(16-c)+ 2c = 48

Then 64 - 4c + 2c = 48

Then 2c = 64 - 48 = 16

Then c = 8

Since h = 16 - c then h = 16 - 8 = 8
