### Matrix Transformations
**Problem Statement:**
Suppose \( A \) is a \( 3 \times 5 \) matrix.
**(a)** Find a \( 3 \times 3 \) matrix \( E_1 \) such that \( E_1A \) is the result of multiplying row 3 of \( A \) by 2.
**Equations and Explanation:**
\[
E_1 = \begin{bmatrix}
1 & 0 & 0 \\
0 & 1 & 0 \\
0 & 0 & 2
\end{bmatrix}
\]
\[
\begin{bmatrix}
1 & 0 & 0 \\
0 & 1 & 0 \\
0 & 0 & 2
\end{bmatrix}
\begin{bmatrix}
a & b & c & d & e \\
f & g & h & i & j \\
k & l & m & o & p
\end{bmatrix}
\]
---
**(b)** Find a \( 3 \times 3 \) matrix \( E_2 \) such that \( E_2A \) is the result of replacing row 2 of \( A \) with 6 times row 1 added to row 2.
**Equations and Explanation:**
\[
E_2 = \begin{bmatrix}
1 & 0 & 0 \\
6 & 1 & 0 \\
0 & 0 & 1
\end{bmatrix}
\]
\[
\begin{bmatrix}
1 & 0 & 0 \\
6 & 1 & 0 \\
0 & 0 & 1
\end{bmatrix}
\begin{bmatrix}
a & b & c \\
d & e & f \\
g & h & i
\end{bmatrix}
\]
---
**(c)** Find a \( 3 \times 3 \) matrix \( M \) so that \( MA \) is the matrix that results after performing the operations in part (a) and then part (b) (in that order) on \( A \).
**Equations and Explanation:**
\[
M = \begin{bmatrix}
1 & 0 & 0 \\
0 & 1 & 0 \\
