Two routes are represented by \(3x+y=20\) and \(x+y=12\). At which point will the routes meet?रेखाएँ \(3x+y=20\) और \(x+y=12\) से दो मार्ग दर्शाए गए हैं। मार्ग किस बिंदु पर मिलेंगे?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Point \(\left(4,8\right)\)बिंदु \(\left(4,8\right)\)
Subtracting the equations gives \(2x=8\), so \(x=4\) and \(y=8\). Whatever the context, the intersection point is the solution.दोनों समीकरण घटाने पर \(2x=8\), इसलिए \(x=4\) और \(y=8\)। संदर्भ कोई भी हो, प्रतिच्छेद बिंदु ही हल है।
