3. After inputting the last coefficient,
press e to solve the 2-VLE.
• After solving, press e or j to
return to the coefficient entering display.
You can use @ h to solve the 2-
VLE, regardless of the cursor position.
Example 2
x +y-z = 9 x = ?
6x+6y-z = 17 Ò y = ?
14x-7y+2z = 42 z = ?
det(D) = ?
1. Press b 3 1 to select 3-
VLE of the EQN mode.
2. Enter the value of each coefficient
(a1, etc.)
1 e 1 e S 1 e 9 e
6 e 6 e S 1 e 17 e
14 e S 7 e 2 e 42
• Coefficients can be entered using ordinary arithmetic operations.
• To clear the entered coefficients, press j.
• Press d or u to move line by line. Press @ d or @
u to jump to the last or top line.
3. After inputting the last coefficient, press e to solve the 3-VLE.
• Press d to display the det(D).
• After solving, press e or j to
return to the coefficient entering display.
You can use @ h to solve the 3-
VLE, regardless of the cursor position.
