1. Recall what variable represents.
2. Filter algebraic solutions by domain and context.
3. State valid solution in context.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Algebraic roots that violate rate, distance, time, or geometry context.
