समीकरणों (8x-3y=25) और (2x+3y=17) से (x) का मान क्या है?
What is the value of (x) from (8x-3y=25) and (2x+3y=17)?
Explanation opens after your attempt
B. (x=4)
Concept
Adding both equations gives (10x=42). Therefore \(x=\frac{21}{5}\).
Why this answer is correct
The correct answer is B. (x=4). Adding both equations gives (10x=42). Therefore \(x=\frac{21}{5}\).
Exam Tip
दोनों समीकरण जोड़ने पर (10x=42) मिलता है। इसलिए \(x=\frac{21}{5}\) है।
