Which point lies on both lines \(3x-2y=4\) and \(x+4y=22\)?कौन-सा बिंदु दोनों रेखाओं \(3x-2y=4\) और \(x+4y=22\) पर स्थित है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Point \(\left(\frac{15}{4},\frac{73}{16}\right)\)बिंदु \(\left(\frac{15}{4},\frac{73}{16}\right)\)
From \(x+4y=22\), \(x=22-4y\), and substituting in the first equation gives \(y=\frac{73}{16}\). Then \(x=\frac{15}{4}\).\(x+4y=22\) से \(x=22-4y\), और पहले समीकरण में रखने पर \(y=\frac{73}{16}\)। फिर \(x=\frac{15}{4}\) है।
