Answer: y2/4 - x2/5
Step-by-step explanation:
![\huge{\boxed{\sf{y= 12 - 6x}}}](https://tex.z-dn.net/?f=%5Chuge%7B%5Cboxed%7B%5Csf%7By%3D%2012%20-%206x%7D%7D%7D)
<u>Step by step explanation:</u>
Step 1:
![2x + \dfrac{y}{3} = 4](https://tex.z-dn.net/?f=2x%20%2B%20%20%5Cdfrac%7By%7D%7B3%7D%20%20%3D%204%20)
Step 2:
![\implies \dfrac{2x \times 3 + y}{3} = 4](https://tex.z-dn.net/?f=%20%5Cimplies%20%5Cdfrac%7B2x%20%5Ctimes%203%20%2B%20y%7D%7B3%7D%20%20%3D%204)
Let take LCM
Step 3:
![\implies \dfrac{6x + y}{3} = 4](https://tex.z-dn.net/?f=%5Cimplies%20%20%5Cdfrac%7B6x%20%2B%20y%7D%7B3%7D%20%20%3D%204)
Step 4:
![\implies6x + y = 4 \times 3](https://tex.z-dn.net/?f=%5Cimplies6x%20%2B%20y%20%3D%204%20%5Ctimes%203)
Step 5:
![\implies6x + y = 12](https://tex.z-dn.net/?f=%5Cimplies6x%20%2B%20y%20%3D%2012)
Step 6:
![\blue{\implies y= 12 - 6x✓}](https://tex.z-dn.net/?f=%5Cblue%7B%5Cimplies%20y%3D%2012%20-%206x%E2%9C%93%7D)

Answer:
3 1/3 gum balls per friend
Step-by-step explanation:
Packs of gum balls Pete has = 4
Each pack = 5 gum balls
Total gum balls Pete has = Number of packs of gum balls × Number of gum balls in each pack
= 4 × 5
= 20 gum balls
Pete gives the same number of gum balls to 6 friends.
Each friend gets = Total gum balls / number of friends
= 20 gum balls / 6 friends
= 3 2/6 gum balls per friend
= 3 1/3 gum balls per friend
