.
1. Define the equation on the
EQUATION SOLVER
screen.

$ : (if necessary)
2. Enter the equation.
- t
1 6 =
b I 6
Done
b b
3. Use
bound
to limit your
answer to a negative one
(between M16 and 0).
# " a

4. Solve for
X
.
# b
5. The guess,
X=10
, is not
between the limit bounds.
You must clear or change it.
(This step uses a different
guess, M6.)
