title: Solution of linear first-order equations without matrix inversion.
abstract: The need to solve linear first-order equations frequently occurs in several areas of analytical chemistry. Several numerical methods are available to solve these systems of equations but are cumbersome and time-consuming when the number of unknowns becomes greater than three. A simple matrix method is presented that avoids the need to calculate determinants or to invert matrices.
