Solve this system for equations (if the system is dependent, find the complete solution)
1: 3x+2y-z=2
9x-4y+3z=3
-3x+6y-2z=4
2: x-y+3z=1
3x+2y-z=8
6x+5y-4z=17
3Ã3 Systems Elimination by Addition
1) 2Ã+5y-2z=7 2) -2y-3z=13 3) -4z=20
Please don't leave out any steps; because I need to be able to know how to get the same results myself.
