Getting Started: Systems of Linear Equations

Use the Matrices application to solve the system of linear
equations:
X + 2Y + 3Z = 3
2X + 3Y + 4Z = 3
Enter the coefficients as elements in a matrix, and then use
to find the reduced row-echelon form.
Steps
1. Run the Matrices
application.
2. Display the
menu, and select the
matrix.
