Question

for what value of k the pair of linear equation 3 X + y is = 3 and 6 X + K y= 8 does not have a solution​

Answer 1

Answer:

Step-by-step explanation:

3x+y-3=0.................(1)

6x+ky-8=0..............(2)

here a1=3,b1=1,c1=3 in equation .....(1)

        a2=6,b2=k,c2=8 in equation( 2)

now for the given pair to have a unique solution : a1/a2is not equal to b1/b2

i.e.,      3/6is not equal to 1/k

i.e.,     k is not equal to 6

therefore , for all the value of k, except 6, the given pair of equations will have a unique solution
