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
C. (x=5)
Concept
From the first equation use (y=4x-17). Then (2x+3(4x-17)=19) gives (x=5).
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).
Exam Tip
पहले समीकरण से (y=4x-17) रखें। फिर (2x+3(4x-17)=19) से (x=5) मिलता है।
