What is the miles-per-gallon rating of this car?
How many miles for 1 gallon?
4.8 gallons are used for 100 miles. So

1 gallon - x miles
![4.8x = 100](https://tex.z-dn.net/?f=4.8x%20%3D%20100)
![x = \frac{100}{4.8}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B100%7D%7B4.8%7D)

7(y) = 7(-³/₇.x) + 7(3)
7y = -3x + 21
3x + 7y = 21
