What is the solution of (4x-y=13) and (x+2y=14) on the graph?ग्राफ पर (4x-y=13) और (x+2y=14) का समाधान कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((4,3))((4,3))
From the first equation, (y=4x-13). Substituting gives (x+2(4x-13)=14), so (x=4) and (y=3). The intersection point is the graphical solution.पहले से (y=4x-13), दूसरे में रखने पर (x+2(4x-13)=14), इसलिए (x=4) और (y=3)। प्रतिच्छेद बिंदु ही ग्राफीय हल है।
