Question

For what value of k , the pair of linear equations 4x+6y-1=0 and 2x+ky-7=0 represents parallel lines-​

Answer 1

Answer:

k=3

Step-by-step explanation:

For given system of equations to have parallel lines,

a1/a2 = b1/ b2 is not equal to c1/c2

Here, a1=4 , a2=2

b1=6 , b2=k

c1=1 , c2=7

So, a1/a2=b1/b2

4/2=6/k

2k = 6

k = 3
