समीकरणों (5x-6y=11) और (3x+2y=9) में (y) हटाने के लिए दूसरे समीकरण को किससे गुणा करना चाहिए?
In (5x-6y=11) and (3x+2y=9), by what should the second equation be multiplied to eliminate (y)?
Explanation opens after your attempt
D. (3)
Concept
Multiplying the second equation by (3) gives (6y). It cancels with (-6y) in the first equation.
Why this answer is correct
The correct answer is D. (3). Multiplying the second equation by (3) gives (6y). It cancels with (-6y) in the first equation.
Exam Tip
दूसरे समीकरण को (3) से गुणा करने पर (6y) मिलेगा। यह पहले समीकरण के (-6y) के साथ हट जाएगा।
