Question

if the equation kx-2y=3 and 3x + y= 5 represent two intersecting line at unique point, then find the value of k?​

Answer 1

Answer:

for unique values,

a1/a2 is not equal to b1/b2

here, a1=k, a2=3, b1=-2, b2= 1

=> k/3 is not equal to -2/1

=> k is not equal to (-2×3)

=> k is not equal to -6

Thus the value of k is equal to all real numbers excluding -6.
