Question

the pair of linear equation 3 X + 7y=k and 12 X + 2 k y equal to 4 k + 1 do not have any solution if k =
​

Answer 1

Answer:

k =(8.3x)

Step-by-step explanation:

3x + 7y=k, 12x+2ky=4k+1

LHS, 3x+7y=k

3x +7y-k..

RHS, 12x+2ky=4k+1

12x+2ky-4k+1...

now by comparison..

3x+7y-k that can be written as k-7y-3x=12x+2ky-4k+1

-7y-3x-12x=2ky-4k-k+1

-7y-15x=2ky-5k+1

-7y-15x/2y=k-5k+1

-3.5-15x=-4k+1

-3.5-1-15x=-4k

-2.5-15x=-4k

(-2.5-15)x=-4k

k=(-2.5-15)x/-4

k=(8.3x)..
