We just have to isolate a. We need to move the a to the right. Do you know how to do that?

Ok, so how do you think we have to move the 'a' from -17/a to the right with -17?

And that's why we get rid of them, To get rid of it, we just have to multply a on both sides. -17/a is -17 divided by a. When we multiply a into it, it cancels out and leaves us with -17. Now we multiply a on the other side and it gives us -17a.
