•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.

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