Verifying a Supply Chain Labor Scaling Factor

A logistics supervisor at a corporate distribution center is auditing a labor-efficiency model represented by the formula: ${}9y + 2 = 6y + 3$ where yy is the warehouse labor scaling factor. A junior operations analyst has proposed setting this scaling factor to y=43y = \frac{4}{3}.

To ensure the analyst's proposal is mathematically sound, you must verify if y=43y = \frac{4}{3} is a valid solution to the model's formula.

Write a short essay that addresses the following:

  1. Identify and describe the standard three-step mathematical strategy used to determine if a specific value is a solution to a linear equation.
  2. Apply this strategy step-by-step to the formula ${}9y + 2 = 6y + 3$ with the proposed value y=43y = \frac{4}{3}. Show your complete algebraic calculations for each step of the process.
  3. State the final simplified mathematical statement, explain what it means in terms of the validity of the equation, and draw a final conclusion on whether the analyst's proposed value of y=43y = \frac{4}{3} is a valid solution.
