    'In algebra, like terms are terms that have the same variables and powers.' from google. so in your expression the like terms are 9C and 4c, and -6D and -3D

    you just need to add 9C to 4C. You will get 13C now add -6D and -3D, you will get -9D.

    Okay, so here's the thing, I actually did do the equation, but my teacher said that she wasn't clear about what my answer was so.

    What I did was: 9c+4c-6d-3d 9c+4c=13c -6d-3d=-9d 13c-9d 9c+4c+6d-3d 13c+13d

    I don't really understand what you did in last and previous lines. The 13C-9D is correct. I think that's why your teacher wasn't clear about the answer.

    Ohh okay, so you think that if I resubmit it to her explaining how I made the mistake and showing her what is right she will give the points back?

    No, but I did email her asking her if I could fix what I did wrong and resubmit it to her.

    there shouldn't be anything in this new solution to not return you points back. If I were you, I would do the same way as I wrote you.

    Okay, I will. I'm also going to explain why I was wrong so she knows what I did to get the correct answer lol.

    I did have the answer correct, but then I put in another answer saying it was the "modified version" that is why she must have taken the point away.

    So, I bet if I send her an email and explain that the answer is 13C-9D, I'll get my point back.

    i hope so. anyway there is no mistake in it. Some teachers (like my little brother's one) take points because they don't like the explanation, but here must be no mistake and the explanation is very detailed in my opinion.
