यदि (kx+3y=25) और (x-y=2) का हल (x=5,\ y=3) है, तो (k) का मान क्या है?
If (kx+3y=25) and (x-y=2) have solution (x=5,\ y=3), what is the value of (k)?
Explanation opens after your attempt
A. \(k=\frac{16}{5}\)
Concept
Substitute the given solution in (kx+3y=25). (5k+9=25), so \(k=\frac{16}{5}\).
Why this answer is correct
The correct answer is A. \(k=\frac{16}{5}\). Substitute the given solution in (kx+3y=25). (5k+9=25), so \(k=\frac{16}{5}\).
Exam Tip
दिए हल को (kx+3y=25) में रखें। (5k+9=25), इसलिए \(k=\frac{16}{5}\)।
