# Algebra 2 solving systems?

Can someone help me out here? I appreciate any help.
Solve the system by elimination
-2x +2y + 3z =0
-2x -y + z = -3
2x + 3y + 3z = 5
Solve the system by substitution
-x-y-z= -8
-4x + 4y + 5z = 7
2x + 2z = 4
I have two examples here because I need to know how to solve by elimination and...

Solve the system by elimination

-2x +2y + 3z =0

-2x -y + z = -3

2x + 3y + 3z = 5

Solve the system by substitution

-x-y-z= -8

-4x + 4y + 5z = 7

2x + 2z = 4

I have two examples here because I need to know how to solve by elimination and substitution. I've tried working these problems out in my notebook but always fail. I have a big test coming up and need to be able to work these kinds of problems. Thanks!
