Hello,
the first step should be to distribue:
-4(3-5x)= -12+20x
Teh resolution may be:
-4(3-5x)>=-6x+9
==>-12+20x>=-6x+9
==>20x+6x>=9+12
==>26x>21
==>x>=21/26
But an other way may be used:
-4(3-5x)>=-6x+9
==>3-5x<= -6x/(-4)+9/(-4)
==>-5x-3/2 x<=-9/4 -3
==>-13/2 x <=-21/4
==>x>= -21/4 *(-2/13)
==>x>=21/(2*13)
==>x>=21/26
Distance = speed x time
2.257 x 9.111 = 20.563527 or 20

First car: 35 gallons
Second car: 15 gallons
<u>Step-by-step explanation:</u>
Assuming 
to be the gas consumed by 1st car and 
to be the gas consumed by 2nd car.
We know that:
Distance traveled = fuel efficiency × gas consumed
So 
Therefore, first car consumed 35 gallons while second car consumed 15 gallons.
