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
Correct Answer

A. \(y=\frac{69}{17}\)

Step 1

Concept

Multiply the first equation by (2) and add the second. \(x=\frac{58}{17}\) and \(y=\frac{69}{17}\).

Step 2

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 \(y=\frac{69}{17}\).

Step 3

Exam Tip

पहले समीकरण को (2) से गुणा कर दूसरे से जोड़ें। \(x=\frac{58}{17}\) और \(y=\frac{69}{17}\)।
