Which is the correct intersection point for \(4x-y=11\) and \(x+y=7\)?रेखाएँ \(4x-y=11\) और \(x+y=7\) के लिए सही प्रतिच्छेद बिंदु कौन-सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \( \left(\frac{18}{5},\frac{17}{5}\right) \)\( \left(\frac{18}{5},\frac{17}{5}\right) \)
Adding \(x+y=7\) and \(4x-y=11\) gives \(5x=18\). Hence \(x=\frac{18}{5}\) and \(y=\frac{17}{5}\).\(x+y=7\) और \(4x-y=11\) जोड़ने पर \(5x=18\) मिलता है। इसलिए \(x=\frac{18}{5}\) और \(y=\frac{17}{5}\) है।
