समीकरणों (7x+2y=32) और (3x-4y=-6) से (y) का मान क्या है?
What is the value of (y) from (7x+2y=32) and (3x-4y=-6)?
Explanation opens after your attempt
A. \(y=\frac{69}{17}\)
Concept
Multiply the first equation by (2) and add the second. \(x=\frac{58}{17}\) and \(y=\frac{69}{17}\).
Why this answer is correct
The correct answer is A. \(y=\frac{69}{17}\). Multiply the first equation by (2) and add the second. \(x=\frac{58}{17}\) and \(y=\frac{69}{17}\).
Exam Tip
पहले समीकरण को (2) से गुणा कर दूसरे से जोड़ें। \(x=\frac{58}{17}\) और \(y=\frac{69}{17}\)।
