Question

For which value of k will the following pair of lincar equations have no solution?
3x+y=1
(2k-1).x + (k-1) y = 2k + 1

plz answer ..............​

Answer 1

Answer:

two linear equation won't have solution when they are parallel.if they are parallel then slopes of each line are equal

by equating both slopes

-1/3=-(k-1)/(2k-1)

2k-1=3k-3

k=2
