Letter Grid 1

Letters stand for numbers.

Same letters are same numbers.

Numbers in squares are row and column sums.

Arrows point to the sums.

What are the values? \mathbf{K} = \underline{\;\;\;\;\;\;\;\;} \ \mathbf{L} = \underline{\;\;\;\;\;\;\;\;} \ \mathbf{M} = \underline{\;\;\;\;\;\;\;\;} \ \mathbf{P} = \underline{\;\;\;\;\;\;\;\;} \ \mathbf{X} = \underline{\;\;\;\;\;\;\;\;}
