3. the 3 is the number of gallons, and the "d" is the cost per gallon.

the g is the number of gallons and the "3" is the cost per gallon.

Explanation:

3g + d = (something).

g + 3d = (something).

Let's multiply every number by 2 as example.

6g + 2d = 2

2g = 6d = 2

(change it to x and y)

6x + 2y = 2

2x + 6y = 2

(0.25, 0.25)

Answer 2

1) 3d
2) 9g
3) -coefficient-variable c=3 v=d
4) -coefficient-variable c=9 v=g
