Answer:

Addition

Step-by-step explanation:

Since you are trying to make x the subject, you need to "get rid" of the -2. So, because it is a negative number, you add 2 to make it 0, which is added to both sides, making x = 7.

Hope this helps!

The answer should 7, because you need to add 2 to both side in order to solve for X. So addition would be the operation.
