linear systems


Summary

Inconsistent

  • No solutions

Consistent

  • Exactly one solution
  • Infinitely many solutions

Concept

Linear equation in standard form

Collection of linear equations

a linear system is homogeneous when all b=0

General solution

  • Needed when there are infinite solutions, the variables are expressed in terms of parameters

Application
