Math Problem Statement

\dfrac x{-8}\geq-5

Solution

To solve the inequality:

x85\frac{x}{-8} \geq -5

We follow these steps:

Step 1: Eliminate the denominator

Multiply both sides of the inequality by 8-8. Remember, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality sign:

x(5)×(8)x \leq (-5) \times (-8)

x40x \leq 40

Final Answer:

x40x \leq 40
