Understanding the Equations
The system of equations provided is:
1. X + Y + Z = 1
2. X - Y + 2Z = 1
3. X - Y + 2Z = 5
4. 2X - 2Y + 3Z = 1
Analyzing the Third Equation
- The second and third equations (X - Y + 2Z = 1 and X - Y + 2Z = 5) contradict each other.
- This indicates that the system of equations is inconsistent, meaning there is no solution that satisfies all equations simultaneously.
Implications of Inconsistency
- When a system is inconsistent, it suggests that the geometric interpretation of the equations involves lines or planes that do not intersect at any point.
- In this case, since two equations yield different results for the same expression, they represent parallel planes in three-dimensional space.
Conclusion
- Since the equations are contradictory, it is impossible to find values for X, Y, and Z that satisfy all four equations.
- Therefore, the answer to the system of equations is that there is no solution.
