Walkthrough
Full solution stays hidden until you ask for it.
1. Simplify both sides.
2. If variables cancel and a false statement remains, no solution.
3. If variables cancel and a true statement remains, infinitely many solutions.
4. Otherwise solve for the single value.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
