Let A = [-3 4] and b = [bā].
[6 -8] [bā]
Show that the equation Ax = b does not have a solution forsome choices of b, and describe the set of all b for which Ax = b does have a solution.
How can it be shown that the equation Ax = b does not have a solution for some choices of b?
a. Row reduce the augmented matrix [A b] to demonstrate that [A b] has a pivot position in every row.
b. Row reduce the matrix A to demonstrate that A does not have a pivot position in every row
c. find a vector b for which the solution to Ax = b is the identify vector.
d. find a vector x for which Ax = b is the identify vector.
e. row reduce the matrix A to demonstarate that A has a pivot position in every row.
