Here is the full question :
Cecile packages snack mix at a health food store.
She uses 1/3 of her supply of sunflower seeds to make a salted snack mix and 2/9 of her supply to make an unsalted snack mix. If Cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply?
Let x = Cecile's supply
1/3 of x = 1/3x
2/9 of x = 2/9x
1/3x + 2/9x = 10
adding the fraction together gives 5/9
5/9 x = 10
solve for x = 18 pounds
