At which point will the lines \(5x+3y=31\) and \(x+y=7\) intersect?रेखाएँ \(5x+3y=31\) और \(x+y=7\) किस बिंदु पर प्रतिच्छेद करेंगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Point \(\left(5,2\right)\)बिंदु \(\left(5,2\right)\)
Substituting \(\left(5,2\right)\) gives \(5\left(5\right)+3\left(2\right)=31\) and \(5+2=7\). If both equations are true, that is the intersection.\(\left(5,2\right)\) रखने पर \(5\left(5\right)+3\left(2\right)=31\) और \(5+2=7\)। दोनों समीकरण सत्य हों तो वही प्रतिच्छेद है।
