Question

1. If a pair of linear equations in two variables 3x + 2 y = 4and 6x - ky = Shave Infinitely many
solutions, then the value of kis​

Answer 1

Answer:

hope its help ful

Step-by-step explanation:

The equations are

3 x+4 y−k=0

9 x+12y−6=0

Here, a1=3,b1=4,c1=−k

and a2=9,b2=12,c2=−6

For the system to have infinite solution if

a2a1=b2b1=c2c1

⇒93=124=−6−k

⇒3 k=6

⇒k=2
