Work for 2 days trying to solve a Level 2 foobar problem and then realize I need to know linear algebra to solves matrices programmatically... And the results have to be in Fractions

    if you need to solve many of these problems at once or multiple times take a look at numerics. They can help you solve these problems faster. I only know the german term for the algorithm that you need. It is LR-Zerlegung.

    I submitted anyway.

    damn I can't seem to remember how to solve this crap...
    I think you should multiply the matrix and the vector, get the equations (should be 4) and substitute to solve...

    @nocgod actually for this, you + or - each row.

    Eventually it will reduce to something like Cx_n = N
