Dear all it have been many years since I stopped reading maths.

Today I have tried to solve the following equation. K is the only unknown factor. So I tried to keep only K in the right part of the equation and put all the others to the left side. As I am not good in math notations in internet please accept my attached image

Could you please help me?

Best Regards

Alex
