Question

solve this friends:-)))

Answer 1

k x - y = 2

6 x - 2 y = 3

a1 = k

a2 = 6

b1 = - 1

b2 = - 2

c1= 2

c2 = 3

For unique solution

a1/a2 = c1/c2

= k/6 = 2/3

= k = 2/3 × 6 = 4

k is 4

For no solutions :

k ≠ 4

For infinite solutions :

a1/a2 = b1/b2 = c1/c2

Hence the equation does not have infinite solutions for any value of k.
