[buggykong]

I have 6 equations and 6 variables I want to solve for:

What would be the best way to go about solving for Aup, Adown, Bup, Bdown, Cup, and Cdown.

Thanks.

Gauss elimination.
Don't expect anybody to make that trivial, tedious job for you.

the easiest way, and the best way obviously, to do this would be arranging it in a matrix and then using gaussian-jordan elimination to reduce the matrix to echelon form and then you would have the variables and their values.

as arildno said, don't expect anybody to do that for you.
