Given :
Assertion: If x=2k-1 and y=k is a solution of the equation 3x-5y-7=0, then the value of k is 10.
(II) Reason: A linear equation in two variables has infinitely many solutions.
To Find : Correct option
Solution:
Assertion: If x=2k-1 and y=k is a solution of the equation 3x-5y-7=0, then the value of k is 10.
=> 3(2k - 1) -5k - 7 = 0
=> 6k - 3 - 5k - 7 = 0
=> k = 10
Hence Assertion: is correct
Reason: A linear equation in two variables has infinitely many solutions.
CORRECT
but not an explanation for value of k
Both assertion(A) and reason (R) are true but reason(R) is not the correct explanation of assertion(A).
