    You can solve it, but which variable do you wish to solve for?

    Also you can simplfy it

    KYX + KYX = YYP

    2KYX = YYP

    2KX = YP

     2KYX = YYP

     2KX = YP

    Now we need to isolate K

     K = \frac{YP}{2X}

    and we are done..

    Since this is the Linear and Abstract Algebra forum we must assume that at the very least these entities are matrices, in which case they do not commute! (at least not unless we are told that they do)

    Fair point Captain Black.

    I should've also picked up on this given the capitalisation.

    We can still only assume as many visitors post their questions in the wrong sub forum.
