![Title: Matrix Equation Solutions
**Matrix Definitions:**
Let \( A \) and \( C \) be defined as:
\[
A = \begin{bmatrix} 1 & -2 \\ -3 & 7 \end{bmatrix}, \quad C = \begin{bmatrix} 1 & -2 \\ 2 & -3 \end{bmatrix}
\]
**Tasks:**
1. **Find a matrix \( B \) such that \( AB = C \).**
\[
B = \begin{bmatrix} \_,\_ \\ \_,\_ \end{bmatrix}
\]
2. **Find a matrix \( D \) such that \( DA = C \).**
\[
D = \begin{bmatrix} \_,\_ \\ \_,\_ \end{bmatrix}
\]
**Notes:**
- The tasks involve finding matrices \( B \) and \( D \) of suitable dimensions that satisfy the matrix multiplication equations \( AB = C \) and \( DA = C \), respectively.
- Each variable matrix involves two rows and two columns, given the dimensions of \( A \) and \( C \).
Ensure the matrices are compatible for multiplication, where the resulting products equal matrix \( C \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F36a79c17-bf73-44c3-9503-d2f30f855206%2Fe0c334d9-a159-43f9-8a9d-8ae9c94bf339%2Ftako7v_processed.png&w=3840&q=75)
