Answer: 2m+4
Explanation:
To simplify, we need to combine "like terms", which means terms that are similar in that it is either just a number or a coefficient and variable. In this case, 3m and -m are like terms, and -6, 2, and 8 are like terms.
Now, we can combine.
-6 + 3m + 2 -m + 8
-4 + 3m - m + 8
4 + 3m - m
4 + 2m (also can be written as 2m + 4)
hope this helps!
