Answer: The answers are provided below

Step-by-step explanation:

15. 7c + 8d + 2c + 17d

= 7c + 2c + 8d + 17d

= 9c + 25d

16. 4 (2m - 3p) + 12m + 7p

= 8m - 12p + 12m + 7p

= 8m + 12m - 12p + 7p

= 20m - 5p

17. (15j + 9z) - (12j + 6z)

= 15j - 12j + 9z + 6x

= 3j + 15z

18. 3y + 6.7x + y + 2.3x + 10 - 7

= 6.7x + 2.3x + 3y + y + 10 - 7

= 9x + 4y + 3

19. 2b + (-6c) + 5e - 11b + e + 6c

= 2b - 11b - 6c + 6c + 5e + e

= - 9b + 6e
