Someone help with me with this algebra thing the attactments r down below

5. kitkat

6. B4

7. the machine was either switching between snacks or its a malfunction. stickers also may have been messed with

8. possibly? im not sure what the question is exactly asking but i would assume so

9. no it just means snacks are in two different places but sometimes yes it could be a malfunction

10. then it is not a problem. they use the same input and get the same output.
