समीकरणों (2x-y=6) और (x+3y=13) का हल क्या है?

What is the solution of (2x-y=6) and (x+3y=13)?

Explanation opens after your attempt
Correct Answer

D. \(x=\frac{31}{7},\ y=\frac{20}{7}\)

Step 1

Concept

Use (y=2x-6) from the first equation. Substitution gives (7x=31), so \(x=\frac{31}{7},\ y=\frac{20}{7}\).

Step 2

Why this answer is correct

The correct answer is D. \(x=\frac{31}{7},\ y=\frac{20}{7}\). Use (y=2x-6) from the first equation. Substitution gives (7x=31), so \(x=\frac{31}{7},\ y=\frac{20}{7}\).

Step 3

Exam Tip

पहले समीकरण से (y=2x-6) रखें। दूसरे में रखने पर (7x=31), इसलिए \(x=\frac{31}{7},\ y=\frac{20}{7}\)।
