A huge kettle is 1/5 full of water.
If 40 gallons of water are added, the kettle will be 1/3 full.
How many gallons of water does the kettle hold when filled to the top?
Solution to the Problem:

Here is the solution:

The kettle holds 300 gallons of water.

Let x = the number of gallons in the kettle
Then 1/5 x + 40 = 1/3 x
3x + 15*40 = 5x
600 = 2x
300 = x
