Question

The value of k for which the pair of linear equations kx - y = 2 and 6x -2y = 3 has a unique solution​

Answer 1

Answer:

2x-3y = 1

kx+5y = 7

Step-by-step explanation:

There is no single value of k which determines a unique solution. In fact, since the slope of

2x-3y=1 is 2/3, any value of k which makes the slope of the other line different from 2/3 will work.

So, if -k/5 = 2/3 then k = -10/3 and the line

-10/3 x + 5y = 7

Answer 2

Answer:

i have used cross multiplication method

and

k= (1-6x)/2x
