(1) Coefficient name
(2) Element value
(3) Arrow indicates direction you should scroll to view other elements.
• Any time until you input a value for the final coefficient ( c
2
for two
unknowns, d
3
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 coefficients.
Calculation starts and one of the solutions appears as soon as you input a
value for the final coef
ficient.
(1) Variable name
(2) Solution
(3) Arrow indicates direction you should scroll to view other solutions.
• Press the key to view other solutions. Use and to scroll
between all of the solutions for the equation.
• Pressing the key at this point returns to the coefficient input
screen.
Example: T
o solve the following simultaneous equations
2 x + 3 y - z = 15
3 x - 2 y + 2 z = 4
5 x + 3 y - 4 z = 9 ( x = 2, y = 5, z = 4)
