For what value of k, the pair of linear equations 3x - ky + 7 = 0,x - 2y + 5 = 0 has unique solution.
Given pair of linear equations are : 3x - ky + 7 = 0 and x - 2y + 5 = 0 Here, we have a1 = 3, b1 = -k a2 = 1, b22 = -2 For unique solution
∴ The given system of linear equations has unique solution for all real values of k other than 6.
