Find the inverse, if it exists, of the following matrix using row of operations. First, find the reduced echelon form, THEN find the inverse next. Show all steps being separate.
![This is a 3x3 matrix with the following elements:
\[
\begin{bmatrix}
-2 & -3 & 1 \\
-3 & -3 & 1 \\
-2 & -4 & 1
\end{bmatrix}
\]
### Matrix Explanation:
- The matrix consists of 3 rows and 3 columns.
- Each element in the matrix is positioned as follows:
- The element in the first row and first column is -2.
- The element in the first row and second column is -3.
- The element in the first row and third column is 1.
- The element in the second row and first column is -3.
- The element in the second row and second column is also -3.
- The element in the second row and third column is 1.
- The element in the third row and first column is -2.
- The element in the third row and second column is -4.
- The element in the third row and third column is 1.
Matrices like this are often used in various mathematical computations, including solving systems of linear equations, transformations in graphics, and more. The arrangement and values of the elements within the matrix are crucial for these computations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8d07e113-70c7-44ea-a54a-4dad627b44c8%2F9bdeef73-8318-41d6-90a3-c592b2ab7db6%2Fzbr57tx_processed.png&w=3840&q=75)
