Hexagon has 6 sides, each side = 12 so 6x12
I'm in a hurry to get home.
My car is almost out of gas.
I pull into a gas station.
I have $10 in my pocket.
Gas is selling for $2.36⁹ per gallon.
How many gallons can I buy.
=================================
Even better:
My car gets 25 miles to the gallon.
How many miles can I buy ?
X=3x-2.4 because if you substract from one side you have to do it to the other
