SYARAT PERLU DAN CUKUP SISTEM PERSAMAAN LINEAR BERUKURAN m × n MEMPUNYAI SOLUSI

Abstract

This article discusses the necessary and sufficient condition for the system of linear equations Ax = b where A is an m × n matrix, with m < n and b is an n × 1 vector to have a solution. The discussion involves determining the number of single variables by looking at columns lowering rank and determining the value of the single variables.
