Question:

We went to the store last night, and bought three packages of Oreo's. Should the comma be deleted, moved, or kept in this sentence?

Alexis E.
Answer:

The comma should be deleted from the sentence because you are only talking about one item that was bought from the store, not multiple items.

Question:

What is x if 4x = 8 + 4? Describe the steps you took to find the answer (x)?

Alexis E.
Answer:

First, I added 8+4 and 8+4 is 12 (4x=12). The next thing I did was isolate x by dividing both sides by 4 (4x/4=12/4). 4x divided by 4 is x because the 4's cancel each other out. 12 divided by 4 is 3, so x=3.
