✔ 最佳答案
As it stands, question does not make sense and can be read in many ways.
Will take a GUESS at :-
(9x - 8) / (x + 8) + 8x / (x + 8)
(9x - 8 + 8x) / (x + 8)
(17x - 8) / (x + 8)
PS
It would have been a good idea to use brackets to clarify the question.
Because of presentation, you will probably receive many different answers.
