Answer:

8x-9

Step-by-step explanation:

You have to combine like terms in order to simplify this problem.

The like terms you have are 5x, and 3x. If you add 5x+3x, you get 8x.

Now, you do nothing with the 9 because there is nothing to combine it with. For example, if your problem was 5x+3x-9+10, you combine 5x and 3x to get 8x, but now with the 9, you keep the subtraction symbol so it is 10-9, (think of it as -9), and when you finish that, you get 1. Now there are no more symbols so you add, 8x+1.
