2
+ 4C”.
Press A A A =
2 A B y + 4
A C.
3. Press E.
The screen above right appears, indicating that there are 3
variables to be assigned.
Note: If values were assigned to those variables prior to this operation,
then the previously set values will be shown here. For example,
“C = 57” may show up in this
window; this simply indicates
the value of “C” was previously
set to “57”.
4. Enter “4” for variable “A”, and
“5” for variable “B”.
Press 4 E 5 E.
5. When the two known values have been specified, make sure
that the cursor is at the value yet to be determined (in this
case, the value of “C”).
6. Press @ h to
execute the SOLVER. The
value of “C” will be obtained.
* After the solution has been
found, press C to return
to the variable input screen. You may change the numeric
values for the variables and select another unknown variable to
solve.
*To edit the equation, press C on the variable input screen.
The equation input screen allows you to correct or edit the
previously input equation.
