Full solution stays hidden until you ask for it.
1. Write the rational inequality and domain restriction.
2. Use the known denominator sign to clear fractions safely.
3. Solve and express the restricted solution set.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
