If (ax+6y=18) and (2x+3y=9) are coincident lines, what is the value of (a)?यदि (ax+6y=18) और (2x+3y=9) संपाती रेखाएं हैं, तो (a) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (4)(4)
The first equation must be (2) times the second, so (a=4). In coincident lines, all terms change by the same multiplier.पहला समीकरण दूसरे का (2) गुना होना चाहिए, इसलिए (a=4)। संपाती रेखाओं में सभी पद समान गुणक से बदलते हैं।
