This is a systematic way to solve system of equations and is especially helpful when solving very large systems of equations. The first step in using the Gauss-Jordan Elimination Method is to use the system of equations to set up an augmented matrix (a coefficient matrix next to a constant matrix) .

Using technology, matrices provide an efficient way to solve equations, especially multiple equations having many variables. This is true because in any system of equations written as matrix multiplication, Ax = B, the equation can be solved for x as, where matrix A is the coefficient matrix, , and matrix B is the constant matrix, .

Multiply both sides of the matrix equation by the inverse matrix. In order to multiply the matrices on the right side of the equation, the inverse matrix must appear in front of the answer matrix.(the number of columns in the first matrix must equal the number of rows in the second matrix).
