Question
Can you help me solve these three problems and can you show how you did it step by step.
![### Matrix Computations
Given the matrices:
\[
A = \begin{bmatrix}
1 & 1 \\
2 & 3
\end{bmatrix},
B = \begin{bmatrix}
0 & 1 & -1 \\
2 & 0 & 1
\end{bmatrix},
C = \begin{bmatrix}
0 & 1 & 0 \\
-3 & 3 & 1
\end{bmatrix},
\text{and}
D = \begin{bmatrix}
1 & 2 \\
0 & 1 \\
3 & 8
\end{bmatrix}.
\]
Compute the following matrices. If an answer doesn’t exist, write DNE (Does Not Exist).
#### a) \( 2A - B \)
Compute the matrix \( 2A - B \).
#### b) \( 3B + 2C \)
Compute the matrix \( 3B + 2C \).
#### c) \( C - D \)
Compute the matrix \( C - D \).
### Visual Explanation
No graphs or diagrams are provided in this exercise; it is a purely numerical matrix computation task.
### Instructions for Computation
- **Matrix Multiplication:** When computing matrices, ensure dimensions match for valid operations.
- **Matrix Addition/Subtraction:** Only matrices of the same dimensions can be added or subtracted.
- **Scalar Multiplication:** Each entry in the matrix is multiplied by the scalar.
Ensure to follow these rules while solving the matrix computations to avoid errors.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3d7a07fd-0eaf-4cca-88de-0657a73b7fc8%2F073185b3-667b-4bd9-b60c-5e8d75d89752%2Fot4i1am_processed.jpeg&w=3840&q=75)
