समीकरणों (8x-3y=31) और (2x+3y=29) को हल करने पर (y) कितना होगा?

On solving (8x-3y=31) and (2x+3y=29), what is (y)?

Explanation opens after your attempt
Correct Answer

C. \(y=\frac{17}{3}\)

Step 1

Concept

Adding both equations gives (10x=60), so (x=6). From the second equation, \(y=\frac{17}{3}\).

Step 2

Why this answer is correct

The correct answer is C. \(y=\frac{17}{3}\). Adding both equations gives (10x=60), so (x=6). From the second equation, \(y=\frac{17}{3}\).

Step 3

Exam Tip

दोनों समीकरण जोड़ने पर (10x=60), इसलिए (x=6)। दूसरे समीकरण से \(y=\frac{17}{3}\)।
