interpret contradiction or identity after simplification.
Hidden until you reveal it.
Equation must simplify to identity, contradiction, or single solution.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Simplify both sides and collect variable terms.
2. An identity gives infinitely many solutions; a contradiction gives none; otherwise solve for one value.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Only naming solution count without reason.
