Walkthrough
Full solution stays hidden until you ask for it.
1. Check algebraic constraints first.
2. Then check real-world restrictions such as whole numbers, nonnegative values, and maximum capacities.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying invalid without naming the restriction.
