Question

If x = 1 and y = -1 is a solution of the equation 12x – ky = (2k + 1).
Find the value of k.​

Answer 1

Answer:-

Putting the values of x and y inn the equation, we get,

12 × 1 – k × (-1) = (2k + 1)

12 + k = 2k + 1

2k – k = 12 – 1

k = 11

Hence, the value of k is 11.

====================================

Answer 2

Answer:k=11

Step-by-step explanation:

as x=1 and y=-1

12x-ky =(2k+1)

12*1 - k*-1 = 2k +1

12 - -k=2k+1

12-1=2k-k

11=k

k=11
