Solving simultaneous linear equations
1. Press b 6 0 or b 6 1 .
2. Enter the value for each coeffi cient (
• Coeffi cients can be entered using ordinary
arithmetic operations.
• To clear the entered coeffi cient, press j .
• Press u or d to move the cursor up or
down through the coeffi cients. Press @ u or
@ d to jump to the fi rst or last coeffi cient.
3. When all coeffi cients have been entered, press e
to solve the equation.
• While the solution is displayed, press e or
j to return to the coeffi cient entry display. To
clear all the coeffi cients, press @ Z .
