Question

For what value of k, do the equation 3x-2y +8 =0 and 6x + k y = -16 represent coincident lines ? ​

Answer 1

Answer=>

k = 2

For k = 2, the two equations 3x-y+8=0 and 6x-ky=-16 represent coincident lines.

Hence,

for the system of equations to have a unique solution the value of k must not be 6. So, the answer is k can have any value other than 6.
