Question

The value of k the pair of equation 3x+4y=8,kx+3y=6 has unique solution

Answer 1

Step-by-step explanation:

Given pair of linear equations are 3x+4y=8,Kx+3y=6 here the equations have unique solution

so they are interesting lines

The condition for intersecting lines=a1/a2#b1/b2

Here a1=3,A2,=k,b1=4,b2=3

so,

3/k not equal to 4/3

after cross multiplication we get,

9#4k. (#indicates not equal to)

so,

k#9/4
