Hello There!
The correct answer would be "B" this is because we are taking 6 and multiply it by our x column which is the "in" column and adding 1 to what we get.
Just convert all your measurements. 1gallon is 4 quarts. So 9 gallons= 36qt and 6 gallons= 24qt so the question becomes 36qt+1qt+24qt+1qt=62qt or 15.5 gallons.
First set up the equation 12x-7=4x+9
Get all the x's on one side and number on one side so you have 8x= 16
You get X=2
