Answer:

adjust city gallons to 3 gallons and freeway to 7 gallons

make your line in the chart:

3 | 10-3 = 7 | 3(25) = 75 | 7(40) = 280 | 75 =280 =355 | 355 | yes

Step-by-step explanation:

x = city gallons

y = freeway gallons

x+y = 10 then y = 10-x

25x+40y = 355

substitute for y

25x+40(10-x) = 355

25x+400-40x = 355

-15x+400 = 355

subtract 400 from each side

-15x = -45

divide both sides by -15

-15x/-15 = -45/-15

x = 3 gallons

y = 7 gallons
