How will the lines (2x+y=7) and (6x+3y=20) appear on a graph?ग्राफ में रेखाएं (2x+y=7) और (6x+3y=20) कैसी होंगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Parallel distinctसमांतर अलग-अलग
(\frac{2}{6}=\frac{1}{3}\neq\frac{7}{20}), so the lines are distinct and parallel. This case gives no solution.(\frac{2}{6}=\frac{1}{3}\neq\frac{7}{20}), इसलिए रेखाएं समांतर अलग-अलग हैं। यह स्थिति कोई समाधान नहीं देती।
