You can put this solution on YOUR website! 1x+2y+3z=-5
3x+2y-2z=-13
5x+3y-1z=-1
-----------
If you mean you want to solve using elimination:
Eliminate z first.
Multiply eqn 3 by 2, then subtract from eqn 2.
Multiply eqn 3 by 3, then add to eqn 1
-----
That leaves 2 eqns in x & y.
Can you finish it?
