Which point lies on both lines \(2x+5y=29\) and \(3x-y=7\)?कौन सा बिंदु दोनों रेखाओं \(2x+5y=29\) और \(3x-y=7\) पर स्थित है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((4,3))((4,3))
Substituting ((4,3)) does not give \(2x+5y=29\), so it is not correct; the true solution is \(\left(\frac{64}{17},\frac{73}{17}\right)\). Check a point in both equations.((4,3)) रखने पर \(2x+5y=23\) नहीं, इसलिए यह गलत होता; सही हल \(\left(\frac{64}{17},\frac{73}{17}\right)\) है। विकल्प जांचते समय दोनों समीकरणों में बिंदु रखना जरूरी है।
