Simplify it by how much? To an answer? the first thing you would do is distribute the negative so: -9+7c=0
OpenStudy (anonymous):
I'm guessing so... It says simplify each expression. Well one of the examples to -(20+d) and the website ChaCha said it was -20-d
OpenStudy (anonymous):
Okay, so yeah I guess that's all you need to do. Does that make sense to you?
OpenStudy (anonymous):
So far it does. Thank you!
