Drafting a Standard Operating Procedure for Quality Control Calibration

As part of your onboarding as a junior Quality Assurance (QA) technician at a precision electronics manufacturing facility, you are asked to draft a quick-reference guide for troubleshooting sensor calibration levels. Your first task is to document the standard, step-by-step algebraic procedure to solve the standard tolerance limit equation:

3x44=8{}3|x - 4| - 4 = 8

Write a short training guide explaining how to solve this equation. In your guide, you must explicitly recall and describe:

  1. The mathematical operations needed to isolate the absolute value expression, including the equation's state after each operation is performed.
  2. The rule for splitting the isolated absolute value expression into two separate, equivalent linear equations.
  3. The final calculation steps required to solve for the two values of xx.
