**Answer:**

-2

**Step-by-step explanation:**

Add them up: -14

Divide by how many there are: -14 / 7 = -2

**Answer:**

c=6 They sold a total of 114 cans

**Step-by-step explanation: The ratio is 7:12, so last week, he sold 42 cans, meaning that you need to divide 42 by to get 6 in order to figure out the amount Ellen sold last week. Then do 6 times 12 to get 72 cans sold for Ellen. Add 72 to 42 to get 114 cans sold in total. **

6g + 2d + 5f + 7

Reason - combine terms with the same coefficient.

6 + m/4 = 3 (subtract 6 from both sides)

m/4 = -3 (multiply both sides by 4)

m = -12

Can plug in to original equation to check work:

6 - 12/4 = 3

6 - 3 = 3

3 = 3

The answer m = -12 checks out
