Which point lies on both lines \(x-2y=-5\) and \(2x+y=13\)?कौन-सा बिंदु दोनों रेखाओं \(x-2y=-5\) और \(2x+y=13\) पर स्थित है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Point \(\left(\frac{21}{5},\frac{23}{5}\right)\)बिंदु \(\left(\frac{21}{5},\frac{23}{5}\right)\)
Solving both equations gives \(x=\frac{21}{5}\) and \(y=\frac{23}{5}\). This point lies on both lines.दोनों समीकरण हल करने पर \(x=\frac{21}{5}\) और \(y=\frac{23}{5}\) मिलता है। यह बिंदु दोनों रेखाओं पर है।
