At which point do the lines \(2x+3y=19\) and \(2x-y=7\) meet?रेखाएँ \(2x+3y=19\) और \(2x-y=7\) किस बिंदु पर मिलती हैं?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Point \(\left(4,\frac{11}{3}\right)\)बिंदु \(\left(4,\frac{11}{3}\right)\)
Subtracting the second from the first gives \(4y=12\), so \(y=3\); careful checking is needed. The correct solution is \(\left(5,3\right)\).पहले से दूसरे को घटाने पर \(4y=12\), इसलिए \(y=3\) नहीं बल्कि जाँच जरूरी है। सही हल \(\left(5,3\right)\) है।
