Answer: 23m - 11n
Step-by-step explanation:
First, we combine all like terms
the like terms for m are: 7m, 14m, and 2m
7m + 14m + 2m = 23m
the like terms for n are: -6n and -5n
-6n + (-5n) = -11n
Then, we put them back.
23m - 11n is the final answer
Answer:
23m - 11n
Step-by-step explanation:
7m + 14m - 6n - 5n + 2m = (7m + 14m + 2m) - (6n + 5n)
= 23m - 11n
