$Theresultofevaluatingtheexpressionis - \frac{5}{11} .$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenexpressionis \\ \frac{a + b}{a - b} \\ Also, \\ a = - 3 and b = 8 \\ Wewillevaluatetheexpressionforgivenvaluesof a and b \end{array}$

Step 2. Substitute the value of a and b in the given expression

$\begin{array}{l} At a = - 3 and b = 8, Wehave \frac{a + b}{a - b} as \\ \Rightarrow \frac{- 3 + 8}{- 3 - 8} \\ = \frac{5}{- 11} \\ = - \frac{5}{11} \end{array}$
