Alright, let's distribute first 2(3.5m +1)

to do this, multiply 2 into what's in the parentheses, so 2 x 3.5m is 7m and 2x 1 is 2

So: 2(3.5m+1) -> 7m+2

Now, we have 3-7m+7m+2

The rest is easy now! :) We just combine like terms, let's do variables first:

-7m+7m gives you 0 since they cancel each other out.

now the remaining numbers are :

3+2, which gives you 5.

So, (3-7m)+2(3.5+1) is 5! :D

I hope everything made sense, please ask for any clarifications! :DD

(3 - 7m) + 7m + 2                 :Then, combine like terms  (The -7m and the +7m                                                       cancel out)

5

Your final answer is: 

5
