C  3r-12 =15

Step-by-step explanation:

12 rolls eaten + 15 left = total number of rolls

The total number of rolls cam from 3 packages

total rolls =3 packages

12 rolls eaten + 15 left = 3 packages

Let r = number of rolls in a package

12+15 = 3r

Rearranging

Subtract 12 from each side

12+15-12 = 3r-12

15 = 3r-12

Flipping the left and right side

3r-12 =15
