समीकरणों \(\frac{x}{3}+\frac{y}{5}=4\) और (x-y=6) से (x) का मान क्या है?
What is the value of (x) from \(\frac{x}{3}+\frac{y}{5}=4\) and (x-y=6)?
Explanation opens after your attempt
A. \(x=\frac{39}{4}\)
Concept
Multiply the first equation by (15) to get (5x+3y=60). Using (x=y+6) gives \(x=\frac{39}{4}\).
Why this answer is correct
The correct answer is A. \(x=\frac{39}{4}\). Multiply the first equation by (15) to get (5x+3y=60). Using (x=y+6) gives \(x=\frac{39}{4}\).
Exam Tip
पहले समीकरण को (15) से गुणा कर (5x+3y=60) बनाएं। (x=y+6) रखने पर \(x=\frac{39}{4}\)।
