☸ We are going to simplify this Step-By-Step. ☸

☸ First here is the question you ask:

2n+5−(3n+7)+4n−9

☸ Lets start with this:

=2n+5+−3n+−7+4n+−9

☸ Now lets Combine Like Terms:
(Pst the bold stuff is for Combining Like Terms)

=2n+5+−3n+−7+4n+−9

=(2n+−3n+4n)+(5+−7+−9)

☸ Your answer shall be:

=3n+−11

☸Hope this helps!☸
