Walkthrough
Full solution stays hidden until you ask for it.
1. Identify whether the error is algebraic, branch-related, domain-related, or verification-related.
2. Redo the inverse or verification step correctly.
3. State restrictions needed for the corrected result.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
