    2x - 11y + 21

    Step-by-step explanation:

    First, I would rewrite the equation so that like terms are right next to each other.

    -5x + 7x - 9y - 2y + 18 + 3

    Now, complete the operations like normal.

    -5x + 7x = 2x

    -9y - 2y = - 11y

    18 + 3 = 21

    Since you cannot simplify anymore as there are no like terms left to combine, you are left with your equation and final answer:

    2x - 11y + 21

    Once you combine all the like terms you will be left with this

    2x-11y=21
