key term - Inconsistent system

Definition

An inconsistent system is a set of equations that has no solution. This typically occurs when the equations represent parallel lines that never intersect.

5 Must Know Facts For Your Next Test

  1. Inconsistent systems have no points of intersection, meaning they have no common solution.
  2. Graphically, inconsistent systems are represented by parallel lines in two-variable cases.
  3. For three-variable systems, inconsistency can occur if the planes do not intersect at a common point or line.
  4. Algebraically, an inconsistent system results in a contradiction such as $0 = 1$ when solving the equations.
  5. The determinant of the coefficient matrix in an inconsistent system is zero, but this alone does not confirm inconsistency without further evaluation.
