Answer: And i think your answer might b 21 but i dont know which variable
Explanation:
i can give you how to figure it out but i didn't figure the answers out yet but here's the steps if im not mistaken.
do 6 x 3 and 7 x 2and negative 6 and negative 8 which i believe makes the answer positive when there is two negatives anyway multiply those three first. ( 6 x 3 , 7 x 2 , and -8 x -6) - multiply.
Then you add the answers for the three multiplication steps you did plus the 4 , once you do that which i think is 84? then divide by 4.
Im sorry if this didnt help i tried but i hope this does. I struggle with math myself but still tried.
