1 Reduced Row Echelon Form Matrices and the Calculator

2 Matrix Solution of Systems by Calculator Write the system of equations as an augmented matrix EDIT Input data Menu 1

3 Matrix Solution of Systems by Calculator Menu B:rref( So the solution to Menu 1

4 Example Solve the system: Solution In solving systems of equations, we perform computations with the constants. The variables play no important role until the end, so why not use an augmented matrix. Augmented Matrix rref The solution to this system is (3, 7, -1/2). Standard Form

5 ExamplesUse matrices and your calculator to solve the system.
