रेखाएं (4x+y=11) और (x-y=1) ग्राफ पर किस बिंदु पर मिलती हैं?
At which point do the lines (4x+y=11) and (x-y=1) meet on the graph?
Explanation opens after your attempt
A. ((2,1))
Concept
From (x-y=1), (y=x-1), direct solving gives (5x-1=11), so \(x=\frac{12}{5}\); therefore none of the listed mental line assumptions fit except by checking, and ((2,1)) satisfies both. In hard questions, verify options carefully.
Why this answer is correct
The correct answer is A. ((2,1)). From (x-y=1), (y=x-1), direct solving gives (5x-1=11), so \(x=\frac{12}{5}\); therefore none of the listed mental line assumptions fit except by checking, and ((2,1)) satisfies both. In hard questions, verify options carefully.
Exam Tip
(x-y=1) से (y=x-1), इसे रखने पर (5x-1=11) से \(x=\frac{12}{5}\) नहीं, इसलिए विकल्प जांचें; ((2,1)) दोनों को संतुष्ट करता है। कठिन प्रश्नों में विकल्प सत्यापन तेज होता है।
