Answer:
Replace all occurrences of y with 6x−3 in each equation.
Replace all occurrences of y in 18x−3y=9 with 6x−3 .
18x−3(6x−3)=9
y=6x−3
Simplify 18x−3(6x−3).
9=9
y=6x−3
Remove any equations from the system that are always true.
y=6x−3
Step-by-step explanation:
560 / 28 = 20....so the driver travels 20 miles per gallon
on 35 gallons......35 * 20 = 700 miles <==
or u can also do it this way...
560/28 = x / 35....560 miles to 28 gal = x miles to 35 gal
cross multiply because this is a proportion
(28)(x) = (560)(35)
28x = 19600
x = 19600/28
x = 700 miles <==
so u can either do it by finding the unit rate or by making a proportion. either way will result in the same answer.
