Documenting Failure Zone Calculations

During a technical training assessment on equipment safety, you are asked to document the standard mathematical procedure for finding a machine's failure zones. The zones are modeled by the exact compound inequality from your training manual: 53x1{}5 - 3x \leq -1 or 8+2x5{}8 + 2x \leq 5. Write a short explanation outlining the steps to solve this specific example. Be sure to explicitly recall the solution for each individual inequality, state what happens to the inequality symbol when dividing by a negative number, and provide the final combined solution in interval notation.
