It would be -1

The lowest x value would move to the higher one. If you need help on the steps or don't get it, I can explain it to you.

1. Move the -5x  over to 8x  (tip: when you move the variable it has to be the opposite integer of the original.)

2. Then, add the two variables and you get 13x

3.  Move over the 3 to -16

4. Then, add the integers and you get -13

5. Divide, -13 and 13x, and your answer is x = -1.
