Question

(ii) for which value of k will the following pair of linear equations have no solution?
3x + y = 1
(2k-1)x+(k-1) y = 2k +1​

Answer 1

Hi....

Here is your answer... W

Answer 2

a1/a2=3/(2k-1)

b1/b2=1/(k-1)

c1/c2=1/(2k+1)

condition for no solution

a1/a2=b1/b2 is not equal to c1/c2

a1/a2=b1/b2

3/(2k-1)=1/(k-1)

3(k-1)=1(2k-1)

3k-3=2k-1

3k-2k=-1+3

k=2

hence k=2 for no solution
