Linear Equations: Solutions Using Matrices with Three Variables Solving a system of equations by using matrices is merely an organized manner of using the  elimination method. Example 1 Solve this system of equations by using matrices. The goal is to arrive at a matrix of the following form. To do this, you use row multiplications, row additions, or row switching, as shown in the following. Put the equation in matrix form. Eliminate the

Unformatted text preview: x-coefficient below row 1. Eliminate the y-coefficient below row 5. Reinserting the variables, this system is now Equation (9) now can be solved for z . That result is substituted into equation (8), which is then solved for y . The values for z and y then are substituted into equation (7), which then is solved for x . The check is left to you. The solution is x = 2, y = 1, z = 3....
