Question

find the value of k for which the system of equation x+2y-3=0 And ky+5x+7=0 Has a unique solution​

Answer 1

Hiiii.....friend,

Here is ur answer,

For unique solution,

Ratio of corresponding x coefficient should not equal to corresponding y coefficient.

=> 1/5 not equal to 2/k.

=> K should be equal to 10.

The values of k = 1, 2, 3, 4

:-) Hope it helps u.☺☺☺
