Assuming that you have no typos, deal with like terms first.
3/x - 4/x = -1/x
1/1 = 1
-5+1-5 = -9
This gives me -1/x -9

Unless the plus sign is supposed to be negative, you will not get 2x/3.

Because of apparent typos, I am not even going to deal with the division problem. However, I hope what I did helps. Thanks for asking.
