for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
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
