Answer:
-4m
Step-by-step explanation:
Hey!
==================================================================
First, We should remove the Parentheses.
To remove them, we distribute the negative over (2m + 6m).
⇒ 11m - 7m - (2m + 6m)
⇒ 11m - 7m - 2m - 6m
Work the Problem from Left to Right.
⇒ 4m - 2m - 6m
⇒ 2m - 6m
⇒<u><em> -4m</em></u>
==================================================================
Hope I Helped, Feel free to ask any questions to clarify :)
Have a great day!
