Question

find K if following equations has no solution​

Answer 1

A1 = 3

A2 = 2k - 1

B1 = 1

B2 = k - 1

C1 = - 1

C2 = - (2k + 1)

Then A1/A2 = 3/2k - 1

B1/B2 = 1/k - 1

C1/C2 = - 1/-(2k - 1)

= 1/2k -1

If the equation has no solution

A1/A2 = B1/B2 not = to C1/C2

3/2k-1 = 1/k-1 not = to 1/2k+1

3/2k-1 = 1/k-1

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

3k - 2 = 2k - 1

k= 2
