There are several different methods for solving
these systems.  Please post again stating which
method you are studying,

1. Substitution and elimination
2. Gaussian elimination using matrices with back substitution
3. Complete Gaussian elimination method
4. AX=B matrix method using the inverse matrix
5. Cramer's rule

Solution, regardless of method used: 

{{{(matrix(1,5,x,",",y,",",z))=(matrix(1,5,6,",",1.5,",",3.2))}}}
