    You wanted to know what the method is. It's called the maximum matching algorithm. The page I linked to is one of many that has an explanation of the algorithm. I thought it would be nice to link to another TSR page.

    You will find it explained clearly elsewhere. Do you have a textbook?

    Write down an alternating path.

    J-3=B-6=K-4

    Make the change.

    J=3-B=6-K=4.

    So the improved matching is

    B=6
    J=3
    K=4
    N=5
    and left unchanged A=2.

    I doubt that I'm going to come up with a better explanation than the textbook.
