1. Solve the following system of equations and give a geometrical interpretation of the result.
      x + y + z = 6
      2x + y − 3z = -5
      4x − 5y + z = −3

2. Give a geometrical interpretation of the intersection of the planes with equations
      x + y − 3 = 0
      y + z + 5 = 0
      x + z + 2 = 0
