For what value of k, the pair of linear equations 2x + ky =1 , x – 3y = –3has unique solution.pls tell

Answer»

Step-by-step explanation:

2x+ky=1, x-3y=-3

2x+ky-1=0

x-3y+3=0

unique SOLUTION means

a1/a2 not EQUAL to b1/b2

a1=2, a2=1 and b1=K, b2=-3

2/1 not equal to k/-3

cross MULTIPLYING it we get

k not equal to -6

Hence k can be any number RATHER than -6.
