If Ididn't wrong the values are:
Tell me if they are right please.

Yes they are right.
So u can create a matrix associated to the system. Where in the left side there are the values of the variables and on the right side there are the known values.
| 3 2 -2 | 1| |3 2 -2 | 1 |
| 2 1 4 | 0| by using gauss method u'll have a matrix like this |0 -1/3 16/3 | -2/3|
| 5 3 -5 | 2| |0 0 -7 | 1 |
so u have to create a new system with the new values
| 3x +2y -2z=1
| -1/3y +16/3z=-2/3
and ull have that z= -1/7 y=-2/7 x=3/7
Tell me if u need help
PS: I used the Gauss-Jordan algorithm -->http://mathworld.wolfram.com/Gauss-JordanElimination.html
