Please help me solve the system
3x+2y-2z=14
2x-5y+3z=7
4x-3y+7z=5
================
I would eliminate x first.
Multiply the 1st eqn by 2 and the 2nd by 3, then subtract.
--> eqn in y & z
====================
Multiply the 2nd eqn by 2, subtract from the 3rd eqn.
--> another eqn in y & z
===============
