Let A = 2 1 -6-3 and b = does have a solution. [ ] Show that the equation Ax=b does not have a solution for some choices of b, and describe the set of all b for which Ax = b O A. Row reduce the augmented matrix [ A b] to demonstrate that [ A b ›] has a pivot position in every row. OB. Find a vector b for which the solution to Ax=b is the identity vector. OC. Find a vector x for which Ax=b is the identity vector. O D. Row reduce the matrix A to demonstrate that A has a pivot position in every row. E. Row reduce the matrix A to demonstrate that A does not have a pivot position in every row. 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=b₁ + b₂. (Type an integer or a decimal.)
