Answer:
y = 4x +4
Step-by-step explanation:
-12x + 3y = 12
3y = 12 +12x ......bring x to opposite side and sign changes
y = 12 +12x / 3 .............bring 3 to oppsite side and it would divide
y = 4 + 4x ............result of diving and the answer of ours
y = 4x +4

Suha should buy 150 envelopes from shop 1 because the cost in shop 1 is 0.06 less shop 2.
<u>Step-by-step explanation</u>:
Total number of envelopes = 150
<u>The cost of envelopes :</u>
- Pack of 25 envelopes in shop 1 = 3.49
- Pack of 10 envelopes in shop 2 = 2.10
- Buy 2 packs get 1 pack free in shop 2.
<u>Shop 1 :</u>
The number of packs to buy 150 envelopes = 150 /25 = 6 packs
The total cost to buy 6 packs = 6 × 3.49 = 20.94
The cost of 150 envelopes in shop 1 is 20.94
<u>Shop 2 :</u>
The number of packs to buy 150 envelopes = 150 /10 = 15 packs
- For each 2 packs you get 1 pack free.
- 10 packs + 5 free packs = 15 packs
The total cost to buy 10 packs = 10 × 2.10 = 21
The cost of 150 envelopes in shop 2 is 21
The difference between shop 2 and shop 1 = 21 - 20.94 = 0.06
Therefore, the cost in shop 1 is 0.06 less than shop 2. So, Suha should buy 150 envelopes from shop 1.
