    3x+y-1=0 (2k-1)x +(k-1)y -(2k+1)=0 From here we can find the value of a1,a2,b1,b2,c1 and c2. For no solution a1/a2 = b1/b2 is not equal to c1/c2 Put values of a1,a2,b1......c2. 3/2k-1=1/k-1 is not equal to 1/2k+1 On comparing 3/2k-1 = 1/k-1 3k-3 = 2k-1 (on cross multiplication) K = 2 Hence, k value should be 2 for no solution.
