Question

find the value of k for which the following pair of linear equations has no solution:
X + 2y = 3 and ( k - 1 )x + ( k + 1)y = ( k + 2 )​

Answer 1

Answer:

Step-by-step explanation:

we know that ,

equation will have no solution when

x1/x2 = y1/y2 ≠ z1/z2

1 / k-1 = 2 / k+1

= k+1 = 2k-2

= k =3
