Mathematics Answer, Explanation and Revision Hints
युग्म (wx-6y=4) और (16x-24y=12) का अद्वितीय हल कब होगा? / When will (wx-6y=4) and (16x-24y=12) have a unique solution?
Correct Answer: B. \(w\neq4\). Explanation: अद्वितीय हल के लिए \(\frac{w}{16}\neq\frac{-6}{-24}\) होना चाहिए। इसलिए \(w\neq4\) होगा। / For a unique solution, \(\frac{w}{16}\neq\frac{-6}{-24}\) must hold. Therefore, \(w\neq4\).
