Answer 1

Here we are given that Gracie sold 15x + 4xy in her inventory and Mariella sold -15x +3x -2xy on weekends. We need to find combined inventory.

For that simplify add both the expressions as ,

15x + 4xy + (-15x) + 3x - 2xy

15x + 4xy - 15x + 3x - 2xy

Group like terms ,

(15x + 3x - 15x ) + (4xy - 2xy)

simplify,

3x + 2xy [ required answer]

And we are done!
