Question

For what value of k, the pair of linear equations kx − 4y = 3, 6x − 12y = 9 has infinitely many solutions?

Answer 1

Answer:

answer=2

Step-by-step explanation: so the question is  kx-4y=3 , 6k-12y=9

for infinitely  solution

a1/a2 =b1/b2 = c1/c2

a1/a2 =b1/b2

k/6 = -4/-12

therefore, k=2

similarly , a1/a2 = c1/c2

k/6 = 3/9

k= 2
