समीकरणों \(\frac{x}{2}+\frac{y}{3}=5\) और (x-y=3) का हल क्या है?

What is the solution of \(\frac{x}{2}+\frac{y}{3}=5\) and (x-y=3)?

Explanation opens after your attempt
Correct Answer

A. \(x=\frac{36}{5},\ y=\frac{21}{5}\)

Step 1

Concept

Multiplying the first equation by (6) gives (3x+2y=30). Using (x=y+3) gives \(y=\frac{21}{5}\) and \(x=\frac{36}{5}\).

Step 2

Why this answer is correct

The correct answer is A. \(x=\frac{36}{5},\ y=\frac{21}{5}\). Multiplying the first equation by (6) gives (3x+2y=30). Using (x=y+3) gives \(y=\frac{21}{5}\) and \(x=\frac{36}{5}\).

Step 3

Exam Tip

पहले समीकरण को (6) से गुणा करने पर (3x+2y=30) मिलता है। (x=y+3) रखने पर \(y=\frac{21}{5}\) और \(x=\frac{36}{5}\)।
