✔ 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.

= (9x/[x + 8]) - ([8 + 8x]/[x + 8])
= (9x - 8 - 8x)/(x + 8)
= (x - 8)/(x + 8)

Answer: (x - 8)/(x + 8)

9x/(x + 8) - (8 + 8x)/(x + 8)
= (9x - 8 - 8x)/(x + 8)
= (9x - 8x - 8)/(x + 8)
= (x - 8)/(x + 8)
