Question

For what value of k, the system of equations kx + 2y = 2 and 3x + y = 1 will be coincident?
(A) 2
(B) 3
(C) 5
(D) 6​

Answer 1

Answer:

D) 6

Step-by-step explanation:

coincident ray passes when

a1/a2=b1/b2=c1/c2

And in this question

K/3=2/1=2/1

So, the ratio is 2/1

So, 6/3=2/1

Thus D is the answer
