Question

Find the value of K 2x–y+8=0 and 4x–ky+16=0​

Answer 1

Answer:

IT HAVE INFINTY SOLUTION

SO, A1/A2 = B1/B2 = C1/C2

===> 2/4 = -1/-K

===> 2/4 = 1/K

==> 1/2 = 1/K

SO, K =2

Answer 2

Solution : - 2x - y + 8 = 0 , 4x - ky + 16 = 0 two equations (Given )
K = ?
1st of all multiply by 2 in equation (1)
we, get , 4x - 2y + 16= 0

Now, substracting (4x - 2y + 16 )- ( 4x - ky + 16 ) = 0
=> ky = 2y
K = 2 Answer ✔
