There is one more type of outcome that we didn't encounter in Parts 1 and 2. Solve the following system, and be alert to a different situation. State your conclusion about the solutions to this system, and describe the feature of the equivalent reduced echelon matrix that led you to that conclusion.
x1 + 4x2 + 3x3 = 10
2x1 + x2 - x3 = -1
3x1 - x2 - 4x3 = 11
