Question

Simplify the rational expression. You may want to refer to Example 12 of this8x - 9/9 - 8x

Answer 1

`-1`

Step-by-step explanation

We want to simplify the rational expression given:

`(8x-9)/(9-8x)`

To do this, rewrite the denominator and simplify:

`a-b=-(b-a)`

This implies that:

`\begin{gathered} (8x-9)/(-(8x-9)) \\ \Rightarrow(1)/(-1) \\ \Rightarrow-1 \end{gathered}`

That is the answer.
