  1. Gaussian Elimination
    Solve the following linear systems:
    1. x+2y=3 x+2y=3
      2x+3y=12x+3y=1
    2. x+4y+3z=1 x+4y+3z=1
      x+2y+9z=1x+2y+9z=1
      x+6y+6z=1x+6y+6z=1
    3. x+3y+3z=2 x+3y+3z=2
      3x+9y+3z=33x+9y+3z=3
      3x+6y+6z=43x+6y+6z=4
    4. 4x5y=6 4x-5y=-6
      2x2y=12x-2y=1
    5. x+3y+4z=4 x+3y+4z=4
      x+3y+2z=2-x+3y+2z=2
      3x+9y+6z=63x+9y+6z=-6
