Note:
Matrix
calculations are based
on
the method
of elimination
being widely
used.
However, due
to the
nature
of
numerical
calculations
by
any computer,
an
error
may occur
in
the calculation
of
a
determinant or
an
inverse
matrix
because of
truncation
or
some
other
reasons.
Thus,
the
solutions
x,
y,
and
z
of
the
equations
are
as
follows:
x
=
3,
y
=
-1

z
