If (2x+4y=18) and (x+2y=9), which statement is correct about these two equations?यदि (2x+4y=18) और (x+2y=9), तो इन दोनों समीकरणों के बारे में सही कथन क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: The first equation is (2) times the secondपहला समीकरण दूसरे का (2) गुना है
The first equation is (2(x+2y)=18), so it is (2) times the second. Recognizing proportional equations is also important.पहला समीकरण (2(x+2y)=18) है, इसलिए यह दूसरे का (2) गुना है। समानुपाती समीकरणों को पहचानना भी जरूरी है।
