समीकरणों \(\frac{2x-3y}{5}=1\) और \(\frac{x+y}{2}=6\) से (y) का मान क्या है?
What is the value of (y) from \(\frac{2x-3y}{5}=1\) and \(\frac{x+y}{2}=6\)?
Explanation opens after your attempt
B. \(y=\frac{19}{5}\)
Concept
The equations become (2x-3y=5) and (x+y=12). Substitution gives \(y=\frac{19}{5}\).
Why this answer is correct
The correct answer is B. \(y=\frac{19}{5}\). The equations become (2x-3y=5) and (x+y=12). Substitution gives \(y=\frac{19}{5}\).
Exam Tip
दिए समीकरण (2x-3y=5) और (x+y=12) बनते हैं। प्रतिस्थापन से \(y=\frac{19}{5}\) मिलता है।
