![1. A matriz by any other name¹
Two matrices are row equivalent if one matrix can be changed into another matrix
by a series of elementary row operations.
(a) Are the following matrices row-equivalent?

0232 , M₂ =
5-723
M₁ =
(b) Removing the 2nd column of each matrix gives

Use a computational tool to determine whether or not these matrices are row
equivalent.

(c) Could removing the same column from a pair of equivalent matrices affect row
equivalence? If so, give an example. If not, give a short justification.
(d) Show that the system of equations corresponding to the augmented matrix
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.](https://content.bartleby.com/qna-images/question/b6f0fc2b-ed06-42f6-aea2-7d26d8b1334d/002704e3-e40c-4072-859a-c836c67b79e4/5xev0g_processed.jpeg)
