DUE AT 8 MT Define a variable, set up an equation, then solve.
Lynn put 3 7/8 gallons of gas in her gas tank. If there are now 18 1/6 gallons in the tank, how many gallons did she start with?
x - gallons she started with

14.3 gallons      = 4 + 7.25/25  or 14.29 gallons.

Explanation:

18 1/6 gallons - 3 7/8 = 14.29

18 - 3 = 15

1/6 - 7/8 = 15 - 0.70833333333 = 14.2916666667

You need to be careful here if you use basic subtraction, simply as two minus would change to addition.
