4-1 Simultaneous Linear Equations
Description
You can solve simultaneous linear equations with two to thirty unknowns.
•Simultaneous Linear Equation with Two Unknowns:
a1x1 + b1x2 = c1
a2x1 + b2x2 = c2
•Simultaneous Linear Equation with Three Unknowns:
a1x1 + b1x2 + c1x3 = d1
a2x1 + b2x2 + c2x3 = d2
a3x1 + b3x2 + c3x3 = d3
Set Up
1. From the Main Menu, enter the EQUA Mode.
Execution
2. Select the SIML (simultaneous equation) Mode, and specify the number of unknowns
(variables).
You can specify from 2 to 30 unknowns. To specify more than six unknowns, press
6(n) and then input a value.
3. Sequentially input the coefficients.
The cell that is currently selected for input is highlighted. Each time you input a
coefficient, the highlighting shifts in the sequence:
a1 → b1 → c1 → … an → bn → cn → (n = 2 to 30)
You can also input fractions, complex numbers, and values assigned to variables as
coefficients.
You can cancel the value you are inputting for the current coefficient by pressing i at
any time before you press w to store the coefficient value. This returns to the
coefficient to what it was before you input anything. You can then input another value if
you want.
To change the value of a coefficient that you already stored by pressing w, move the
cursor to the coefficient you want to edit. Next, input the value you want to change to or
press 1(EDIT).
Pressing 3(CLR) clears all coefficients to zero.
4. Solve the equations.
