6m+4 is the answer but the way you do it is by combing like terms so 2m+4m which equals  6m and then subtract the rest which is 7-3 and is 4 I don't know if that's a good explanation but I hope it works

Hello! And thank you for your question!

First we are going to simplify:

2m + 7 - (3 - 4m)

Then simplify what is in the brackets:

2m+7−3+4m

After that, combine like terms:

(2m+4m)+(7−3)

And then finally, simplify:

6m + 4

Final Answer:

6m + 4
