Gauss-Jordan Reduction
Carrying the elimination further so the solution is read directly from the matrix, with no back-substitution at all.
Tag
elimination
Every page in the KEVOS library tagged elimination. 4 pages.
Engineering↗
Systems in Three Variables
Extending elimination to three unknowns, the order in which variables are removed, and back-substitution.
Engineering↗
Systems of Linear Equations: Substitution and Elimination
Two equations in two unknowns, the two elementary methods, and the geometric meaning of a solution as an intersection.
Engineering↗
Resultants and Discriminants
The resultant as a criterion for common roots, the discriminant as a test for repeated roots, and how both are computed in practice.
