(d) Show that the system of equations corresponding to the augmented matrix 6 82 1 3 2 -2 -7 0 has no solutions. (e) [challenge] What could happen to the solution set of a linear system when you remove a row from the augmented matrix? What does this tell you about the effect of removing a row on row-equivalence? (f) [challenge] Determine whether the following statements are true or false. If the statement is true, give a 2 to 3 sentence proof. If the statement is false, give a counter example. i. Row-equivalent augmented matrices have the same solution set. ii. Augmented matrices with the same solution set are row-equivalent.
