Step-by-step explanation:

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

it’s supposed to be -4+45=41
