Question

(k-1)x-y=5 (k+1) + (1-k)y =(3k+1). find the value of k system of linear eq infinitely solution​

Answer 1

Answer:

k = (y+4) / (y-2)

Step-by-step explanation:

(k-1)x-y=5 (k+1) + (1-k)y =(3k+1)

5 (k+1) + (1-k)y =(3k+1)

5k + 5 + y - yk = 3k + 1

2k - yk = ( -y - 4)

yk - 2k = y + 4

k = (y+4) / (y-2)
