Solving systems of linear equations

Click For Summary
SUMMARY

The discussion centers on solving a system of linear equations represented by the equations: x + 3y + z = 4, 2x + 2y + z = -1, and 2x + 3y + z = 3. Participants concluded that there is only one unique solution to the system, specifically x = -1, y = 4, and z = -7. The consensus indicates that the problem statement may contain an error, as it requests a general solution and two particular solutions despite the existence of a single solution.

PREREQUISITES
  • Understanding of linear algebra concepts, specifically systems of equations.
  • Familiarity with methods for solving linear equations, such as substitution and elimination.
  • Knowledge of unique solutions in the context of linear systems.
  • Basic proficiency in mathematical notation and terminology.
NEXT STEPS
  • Study methods for determining the uniqueness of solutions in linear systems.
  • Learn about matrix representation of linear equations and Gaussian elimination.
  • Explore the implications of inconsistent and dependent systems of equations.
  • Investigate the use of software tools like MATLAB or Python's NumPy for solving linear equations.
USEFUL FOR

Students studying linear algebra, educators teaching systems of equations, and anyone interested in mathematical problem-solving techniques.

Homework Statement


x + 3y + z = 4
2x + 2y + z = -1
2x + 3y + z = 3

Find the general solution, and two particular solutions.


The Attempt at a Solution


y = 4; x = -1; z = -7; if I am not mistaken. So how am I supposed to find a general and two particular solutions if there is only one solution?

You can't. There is only one solution. Must be an error in the problem statement.
 
yeah there is only one unique solution.
