2(3k - 1) - (2k + 1)

————————— = 1/2 , k ≠ 2/7

7K - 2

6k - 2 - (2k + 1)

———————— = 1/2

7k - 2

6k - 2 - 2k - 1

——————— = 1/2

7k - 2

4k - 2 - 1

————— = 1/2

7k - 2

4k - 3

——— = 1/2

7k - 2

2(4k - 3) = 7k - 2

8k - 6 = 7k - 2

8k - 7k = -2 + 6

k = -2 + 6

k = 4 , k ≠ 2/7

k = 4

that's the answer with all steps ...
