14 gallons
Step-by-step explanation:
Let us assign the number of gallons that Erick's tank can hold when full as x
Currently, his tank is 1/6th full hence is holding (1/6)x gallons of fuel
When 7 gallons of fuel is added to the tank, it becomes 2/3 full hence holding (2/3)x gallons of fuel
Therefore the 7 gallons represents; (2/3)x – (1/6)x
(2/3)x – (1/6)x = (3/6)x = ½ x = 7
If (1/2)x = 7; what is x
X = 7 * 2 = 14
= 14 gallons
