Question

find the value of k if -1,1 is a solution of the equation 3x-ky=8​

Answer 1

Step-by-step explanation:

3(-1)-k(1)= 8

-3-k= 8

-3-8= k

-11 = k

Answer 2

Answer:

-11

Step-by-step explanation:

Since -1, 1 is the solution of the equation 3x-ky = 8

Therefore,

x= -1

y= 1

Now,

3x - ky = 8

=> 3(-1) - k(1) = 8

=> -3 -k = 8

=> -3-8 = k

=> -11 = k

=> k= -11
