EQUATION
This section is an overview of the EQUATION Icon. To select this icon, highlight it and press L or press 8.
The initial Equation Editor screen has three modes to choose from, Simultaneous, Polynomial, and Solver; this section will give an overview of each mode.
The Simultaneous mode allows you to solve simultaneous linear equations that contain two to six unknowns.
1. Solve the following system of equations:

Press Q to select the Simultaneous mode and press W for three unknowns. The calculator will display a matrix where the coefficients and constants can be entered in to as long as each equation is in standard form. To enter this system of equations (already in standard form) input the following:
•4 L 1 L N 2 L N 1 L
•1 L 6 L 3 L 1 L
•N 5 L 4 L 1 L N 7 L
There are four options at the bottom of the screen, press Q (SOLV). The solution to this system is
