विलोपन विधि से (x+4y=17) और (x+y=8) को घटाने पर (y) का मान क्या मिलेगा?
Using elimination, what value of (y) is obtained by subtracting (x+y=8) from (x+4y=17)?
Explanation opens after your attempt
C. (y=3)
Concept
Subtracting gives (3y=9), so (y=3). Remove equal (x) terms to get (y) directly.
Why this answer is correct
The correct answer is C. (y=3). Subtracting gives (3y=9), so (y=3). Remove equal (x) terms to get (y) directly.
Exam Tip
घटाने पर (3y=9), इसलिए (y=3)। समान (x) पदों को हटाकर सीधे (y) निकालें।
