    I had a look at this yesterday and thought not, but I wasn't certain so I thought I'd keep quiet. Is there a reason you want to make it simpler, or do you just need it in its simplest form?

    It's better to tell what is this for.

    Given two lines:

    y = cx + a and y = dx + b

    I saw that:

    x = - (b - a) / (d - c)
    and
    y = (a*d - b*c) / (d - c)

    As these formulas are the basis of other formulas, it would help me a lot if there was a simplification of the second one.
    I supose the two last formulas are correct...

    Okay so far.

    Goodreams: Your equations for x & y are correct.

    I prefer x = (a - b) / (d - c) or x = (b - a) / (c - d), but youir equation is correct as it stands.
