At which point do the lines (4x+y=11) and (x-y=1) meet on the graph?रेखाएं (4x+y=11) और (x-y=1) ग्राफ पर किस बिंदु पर मिलती हैं?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((2,1))((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.(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।
