For which value of k will the following pair of linear equation have no solution3x+y=1(2k-1)x + (k-1)y =2k +1

Answer»

ANSWER:

Hello!!!

Here is your answer...

No SOLUTION has parallel lines and

a1/a2 = b1/b2≠c1/c2

Here a1=3, a2=2k-1,b1=1,b2=k+1...

So, a1/a2 = b1/b2

3/2k-1 = 1/k+1 (cross multiplication)

3k+3=2k-1

3k-2k= -1-3

K = -4.....

Hope it helps....
