    OK, I'll try to explain.

    Call the trip upstream X and the the trip downstream Y.

    You know it took 10 hours altogether, so that's how you get the first equation:

    X + Y = 10

    Travelling upstream, they travelled at 4km/h, so they travelled 4X km

    Coming back they travelled at 12km/h, so the distance was 12Y km.

    They ended up back where they started, so that's how you get the second equation.

    4X - 12Y = 0

    Word problems are difficult for a lot of people. This site has some examples that may help you.
