Question

for which value of K will the following pqir of linear equation have no sollution........3x+y=1 and (2k-1)x+(k-1)y=2k+1.

Answer 1

so the answer is k is equal to 4

Answer 2

The given equation is ,

3X + Y = 1.............(1)

(2K-1)X + (K-1)Y = 2K+1...........(2)


This equation is in the form of,

a1X + b1Y + C1 = 0 and a2X + b2Y + C2 = 0

a 1 = 3 , b1 = 1 ,C1 = -1

And,

a2 = 2K-1 , b2= K-1 , C2 = -(2K+1)

Then,

We have,

a1/a2 = b1/b2 is not equal to C1/C2

3/2K-1 = 1/K-1 IS NOT EQUAL TO 1/2K+1



SOLVE THIS YOU WILL GET THE VALUE OF K = 2....
