I'm pretty sure the answer to number one is 12g.

Step-by-step explanation:

To combine like terms, you combine all of the same variables.

For example, if you have 5x+7y+5x, you would combine like terms to make 10x+7x.

So for your first problem, we know that the combined like term is 15g. We know that one of the numbers combined was 3g. With that knowledge, you can subtract 15g-3g and get 12g.

I hope this makes sense, and helps you answer your other questions!
