Solving a system in terms of intersecting planes

Click For Summary
SUMMARY

The discussion centers on solving a linear system represented by three equations: x + 4y + z = 0, 4x + 13y + 7z = 0, and 7x + 22y + 13z = 1. The user attempts to manipulate the equations but consistently arrives at contradictions, such as 0=1 and 0=1/6. This indicates that the system does not have a solution, as the planes represented by these equations do not intersect at a common point.

PREREQUISITES
  • Understanding of linear algebra concepts, specifically systems of equations.
  • Familiarity with the geometric interpretation of linear equations as planes in three-dimensional space.
  • Knowledge of methods for solving systems of equations, such as substitution and elimination.
  • Ability to identify contradictions in mathematical proofs and solutions.
NEXT STEPS
  • Study the geometric interpretation of linear systems and how to visualize intersecting planes.
  • Learn about the conditions for the existence of solutions in systems of linear equations.
  • Explore methods for determining the rank of a matrix and its implications for solutions.
  • Investigate the concept of parallel planes and their relationship to systems of equations.
USEFUL FOR

Students and educators in mathematics, particularly those focusing on linear algebra and systems of equations, as well as anyone seeking to understand the geometric implications of intersecting planes.

Homework Statement



x + 4y + z = 0
4x + 13y + 7z = 0
7x + 22y + 13z = 1

Homework Equations


The Attempt at a Solution



x + 4y + z = 0
- 3y + 3z = 0
-6y + 6z = 1

x + 4y + z = 0
-y + z = 0
-6y + 6z = 1

Then whichever way I solve it I have 0=1 or 0=1/6, so where to go from here or is there just no solution?

First of all, the problem statement is NOT just
x + 4y + z = 0
4x + 13y + 7z = 0
7x + 22y + 13z = 1

That's not a "problem", that's a system of equations. What are asked to do with them?
 
Sorry I had only put it in the title of the thread.

Find all solutions of the linear system. Describe your solution in terms of intersecting planes.
