If the equation K / (x + 1) + 3 / (x-1) = 7 (X & # 178; - 1) has no solution, then K=

If the equation K / (x + 1) + 3 / (x-1) = 7 (X & # 178; - 1) has no solution, then K=

The solution is K / (x + 1) + 3 / (x-1) = 7 / (X & # 178; - 1)
That is, K (x-1) + 3 (x + 1) = 7
The equation has no solution, that is, x = 1 or x = - 1
When x = 1, K does not exist
When x = - 1, namely - 2K = 7, namely k = - 7 / 2
That is k = - 7 / 2
