What is the graphical solution of \(4x-y=11\) and \(x+y=7\)?समीकरण \(4x-y=11\) और \(x+y=7\) का ग्राफीय हल क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( (4,3) )( (4,3) )
Substituting ( (4,3) ) gives \(4(4)-3=13\), so checking is necessary. The correct solution is \( \left(\frac{18}{5},\frac{17}{5}\right) \).( (4,3) ) रखने पर \(4(4)-3=13\) नहीं है, इसलिए जाँच जरूरी है। सही हल \( \left(\frac{18}{5},\frac{17}{5}\right) \) है।
