•Any time until you input a value for the final coefficient
(
c2 for two unknowns, d3 for three unknowns), you can
use the [ and ] keys to move between coefficients
on the screen and make changes, if you want.
• Note that you cannot input complex numbers for coeffi-
cients.
Calculation starts and one of the solutions appears as soon
as you input a value for the final coefficient.

Press the ] key to view other solutions. Use [ and ]
to scroll between all of the solutions for the equation.
Pressing the t key at this point returns to the coefficient
input screen.
• Example: To solve the following simultaneous equations
2
x + 3y – z = 15
3
x – 2y + 2z = 4
5x + 3y – 4z = 9
