let A [ -3 4] and b + [ b₁] Show that the equation Ax b does not have a solution for some choices of b,
[6 -8] [ b₂] 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 Г A b has a prot 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 identity vector.
D. Find a vector x for which Ax b is the identity vector. Row reduce the matrix A to demonstrate that A has a pivot position in every row.
E. Describe the set of all b for which Ax b does have a solution. The set of all b for which Ax-b does have a solution is the set of solutions to the equation 0-0b1 + b2 (Type an integer or a decimal.)
