The given equations : k x+ 3 y=k - 3 ; and 12 x +k y=k will have no solution, if the ratios of coefficients of 'x' and that of 'y' are same. That is : if k/12 = 3/k, which implies k*k = 36==> k = - 6, or k = +6. If K = -6, the two given equations modify into two parallel lines represented by,...

If K = -6, the two given equations modify into two parallel lines represented by, 2 x- y = 3 and 2 x- y = 1. which don't meet at all, and thus have no solution. If k= -6, Both the equations, represent the same line 2 x + y = 1 in, which case too, there is no solution. read less
