comment Can mathematica simplify an expression setting simplified answer equal to zero?
But still using that method, when I define a, I want it to fly to the left hand side... as I now know this value it's no longer unknown? Does that make sence? The thing is.. have all these equations ´where a-b==c*d´ and I'm trying to build a matrix, therefore i need to have knowns on one side, and unknowns on the other side. see this: i.imgur.com/jgzo7.png

i have : a - b == c * d c = 1, therefore, by simplifying mathematica outputs: a = d + b Can i output that as 0 = (d+b)/a ? ------------------------------ All known on one side, all unkown on the other side...

comment Can mathematica simplify an expression setting simplified answer equal to zero?
Yeah, but I also have some expressions which equal 1, and I do not want that moved over setting everything to equal zero... Basically I want all unknown on one side. And all that's known (defined) on the other side..

Yeah I tried that... But how can you tell it to reduce so you have constants on one side ?
