यदि (4x-y=17) और (2x+3y=19), तो (x) का मान क्या होगा?

If (4x-y=17) and (2x+3y=19), what will be the value of (x)?

Explanation opens after your attempt
Correct Answer

C. (x=5)

Step 1

Concept

From the first equation use (y=4x-17). Then (2x+3(4x-17)=19) gives (x=5).

Step 2

Why this answer is correct

The correct answer is C. (x=5). From the first equation use (y=4x-17). Then (2x+3(4x-17)=19) gives (x=5).

Step 3

Exam Tip

पहले समीकरण से (y=4x-17) रखें। फिर (2x+3(4x-17)=19) से (x=5) मिलता है।
