solution
x + 2y = 5 ........ (1)
3x + ky -15 =0
3x + KY = 15 ........ (2)
Unique solution
a1 / a2 =/= b1 / b2 = c1 / c2
1 / 3 =/= 2 / K
K =/= 6
K should not be 6 in (2)
Multiple solution
a1 / a2 = b1 / b2 = c1 / c2
1 / 3 = 2 / K = 5 / 15
1 / 3 = 2 / K
K = 2 x 3
K = 6
K must be 6 in (2)
x + 2y = 5 ........ (1)
3x + ky -15 =0
3x + KY = 15 ........ (2)
