Answer:
Hope it helps you
Step-by-step explanation:
Given, the equations are
x-ky = 2 and 3x+2y=-5
From the equations
a1=1 , b1=-k , c1=2, a2=3, b2=2, c2=-5
If the equations have unique solutions then the lines should be intersecting lines
a1/a2 is not equal to b1/b2
1/3 is not equal to -k/2
Therefore , k is not equal to -2/3
