Full solution stays hidden until you ask for it.
1. Identify highest-degree terms in each operation.
2. Multiply or combine leading terms as needed.
3. Check for cancellation before naming degree and leading term.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
