Question: In Exercises 1-3, solve the given system of equations using either Gaussian or Gauss-Jordan elimination. 1. X1 + 2X2 - 3X3 = 9 2X1 -

In Exercises 1-3, solve the given system of equations using either Gaussian or Gauss-Jordan elimination.
1. X1 + 2X2 - 3X3 = 9
2X1 - X2 + X3 = 0
4x1 - X2 + x3 = 4
2. x - y + z = 0
-x + 3y + z = 5
3x + y + 7z = 2
3. X1 - 3X2 - 2X3 = 0
-X1 + 2X2 + X3 = 0
2x1 + 4x2 + 6x3 = 0
