Question

determine whether the system has a unique, no solution or so many solutions, if there is unique solution then find it x - ky =2 , 3x+2y =-5 ​

Answer 1

Answer:

a'=1. b'=-k. c'=2

a"=3. b"=2. c"=-5

a'/a" = 1/3

b'/b" = -k/2

a'/a" is not equal to b'/b"

hence, system has unique solution

1/3 € -k/2

= -k*3 € 1*2

= -3k € 2

= 3k € -2

= k € -2/3

hence k is not equal to -2/3
