    equation, operator

    Hi!

    I have:

    a+b = c*d

    I want to have a and c on one side and b and d on the other. Can I manage this with some kind of operation?

    I'm am very grateful for help.

    Kind regards! /Magnus

    No because both a and b are dependent upon c and d, so there is no way they can be separated. Proof...

     a+b = c*d

    \frac{a+b}{c}=d

    \frac{a}{c}+\frac{b}{c}=d

    \frac{a}{c}=d-\frac{b}{c}

    There is a c on the right side, and there is no way you can get rid of it without having an a on the right side as well.

    Hi!

    I mean some kind of non-arithmetic operator.

    Thanks a lot for your answer. I'm not sure I understand, yet. Similarily, both b and c are dependent on a and d but they can still be separated. I hope someone can help me understand!

    Kind greetings /Magnus
