समीकरणों (8x-3y=25) और (2x+3y=17) से (x) का मान क्या है?

What is the value of (x) from (8x-3y=25) and (2x+3y=17)?

Explanation opens after your attempt
Correct Answer

B. (x=4)

Step 1

Concept

Adding both equations gives (10x=42). Therefore \(x=\frac{21}{5}\).

Step 2

Why this answer is correct

The correct answer is B. (x=4). Adding both equations gives (10x=42). Therefore \(x=\frac{21}{5}\).

Step 3

Exam Tip

दोनों समीकरण जोड़ने पर (10x=42) मिलता है। इसलिए \(x=\frac{21}{5}\) है।
