Question

Find the sum of

(9c+8)+(5x-2)+(3y+7)

Answer 1

9c + 5x + 3y + 13

Explanation:

you can't combine any of the numbers wwith variables because the variables aren't the same but you can combine the other numbers (8, -2, 7)

8 - 2 = 6

6 + 7 = 13

put the equation back together but instead replace the 8, -2, and 7 with 13 giving you

9c + 5x + 3y +13
