Question 791329
 "Goran's gas tank is 1/6 full. After he buys 14 gallons of gas, it is 3/4 full. How many gallons can Goran's tank hold?"
:
Let x = gallons to fill the tank
:
{{{3/4}}}x = {{{1/6}}}x + 14 
multiply by 12
12*{{{3/4}}}x = 12*{{{1/6}}}x + 12(14)
3(3x) = 2x + 168
9x - 2x = 168
7x = 168
x = 168/7
x = 24 gallons 
:
see if that is true
{{{1/6}}}*24 + 14 = 18 gallons which is 18/24 = 3/4 of the tank
