are you sure it doesnt say +4 at the end of the problem?

I would seperate the terms that can go together
4/x - 8 + 1/x - 4
4/x + 1/x - 8 - 4

do you see what I did/

I did really do anything I just rearranged their order.
4/x - 8 + 1/x - 4
4/x + 1/x - 8 - 4        4/x and 1/x have the same denominator, so I can just add them
                                   -8 and -4 are just numbers so I can combine them
5/x -12              is what I would get

multiply 1 with x-8
add them , it will give you 5x-24
