x + y - z = 0

2x - y + 3z = - 5

x + 2y - 3z = 1

check

eq.1   - 3 + 5 - 2 = 0

          5 - 5 = 0    ,  true

eq.2    2( - 3) - 5 + 3(2) = - 5

            - 6 - 5 + 6 = - 5

            - 5 = - 5   ,  true

eq. 3    - 3 + 2(  5) - 3(2) = 1

           - 3 + 10 - 6 = 1

      - 9 + 10 = 1

   1 = 1   ,   true
