<h2>Answer:  9/(x - 1)</h2>

<h3>Step-by-step explanation:</h3>

Because both terms have the same denominator, then we can subtract the numerators upon the same denominator:

⇒ x+1/x-1 - x-8/x-1 = ((x + 1) - (x - 8))/(x - 1)

                             = (x + 1 - x + 8)/(x - 1)     <em>[expand the brackets and simplify]</em>

                             = 9/(x - 1)
