Which is the correct solution for \(2x-3y=1\) and \(x+y=7\)?समीकरण \(2x-3y=1\) और \(x+y=7\) के लिए सही हल कौन-सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Point \(\left(\frac{22}{5},\frac{13}{5}\right)\)बिंदु \(\left(\frac{22}{5},\frac{13}{5}\right)\)
Using \(y=7-x\) from \(x+y=7\), we get \(2x-3\left(7-x\right)=1\). Thus \(x=\frac{22}{5}\) and \(y=\frac{13}{5}\).\(x+y=7\) से \(y=7-x\) रखकर \(2x-3\left(7-x\right)=1\) मिलता है। इससे \(x=\frac{22}{5}\) और \(y=\frac{13}{5}\) है।
