You can define up to ten equations and expressions in Symbolic
view and select those you want to solve together as a system. For
example, suppose you want to solve the system of equations
consisting of:
X
+ Y
= 16 and
2

X – Y = –1

Make sure that both
equations are selected, as
we are looking for values of X and Y that satisfy both
equations.
4. Display Numeric view.

Unlike the example above,
in this example we have no
values for any variable. You
can either enter a seed
value for one of the
variables, or let the
calculator provide a solution. (Typically a seed value is a
value that directs the calculator to provide, if possible, a
solution that is closest to it rather than some other value.) In
this example, let's look for a solution in the vicinity of X = 2.
