Question

for which value of k will following pair of linear equation have no solution

(i) 4x+y=3, (2k-1)x+(k-1)y=2k+1
(ii) x+3y-4=0, 2x+ky=7​

Answer 1

Answer:

if they have no solution then ,

1. 4 /(2k-1)=1/(k-1)

4k-4=2k-1

2k=3

k=3/2

2.1/2=3/k

k=6

we know that for a pair having no solution we have x1/x2=y1/y2

hope it helps u dear☺️☺️☺️
