☸ 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!☸
