समीकरणों (2x+3y=19) और (4x-y=3) का हल क्या है?

What is the solution of (2x+3y=19) and (4x-y=3)?

Explanation opens after your attempt
Correct Answer

B. (x=2,\ y=5)

Step 1

Concept

Use (y=4x-3) from the second equation. Substitution gives (14x=28), so (x=2,\ y=5).

Step 2

Why this answer is correct

The correct answer is B. (x=2,\ y=5). Use (y=4x-3) from the second equation. Substitution gives (14x=28), so (x=2,\ y=5).

Step 3

Exam Tip

दूसरे समीकरण से (y=4x-3) रखें। पहले में रखने पर (14x=28), इसलिए (x=2,\ y=5)।
