![Perform one step of row reduction, in
order to calculate the values for x and y by
back substitution. Then calculate the values for
al and for y. Also calculate the determinant of
the original matrix.
You can let webwork do much of the calculation
for you if you want (e.g. enter 45-(56/76)(-3)
instead of evaluating it and then entering it). You
can also use the preview feature in order to
make sure that you have used the correct
syntax in entering the answer.
(Note: since the determinant is unchanged by
row reduction it will be easier to calculate the
determinant of the row reduced matrix.)
