Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (3x+y=7), (x+2y=9)(3x+y=7), (x+2y=9)
Substituting ((1,4)) makes (3x+y=7) and (x+2y=9) true. The intersection point must lie on both lines.((1,4)) रखने पर (3x+y=7) और (x+2y=9) दोनों सही हैं। प्रतिच्छेद बिंदु दोनों रेखाओं पर होना चाहिए।
