This section is an overview of the EQUATION Icon. To select this icon, highlight it and press l or
press f.
The initial Equation Editor screen has three modes to choose from, Simultaneous, Polynomial, and
Solver; this section will give an overview of each mode.
There are four options at the bottom of the screen, press q(SOLV). The solution to this system is
(1, -1, 2).
Press q(SIML) to select the Simultaneous mode and press w(3) for three unknowns. The
calculator will display a matrix where the coefcients and constants can be entered in, 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
The Simultaneous mode allows you to solve simultaneous linear equations that contain two to six
unknowns.
1. Solve the following system of equations:
