![**Quiz #2: 18 Points**
**MATH 108**
Evaluate the following problems below:
---
**Case I:**
\[ A = \begin{bmatrix} \frac{1}{2} & \frac{5}{3} \\ \frac{1}{5} & \frac{1}{4} \end{bmatrix} \]
\[ B = \begin{bmatrix} 2 & 3 \\ \frac{1}{5} & -3 \end{bmatrix} \]
1. Find \( A + B \)
2. Find \( A - B \)
---
**Case II:**
\[ C = \begin{bmatrix} \frac{1}{6} & \frac{1}{2} \\ \frac{1}{14} & 3 \end{bmatrix} \]
\[ D = \begin{bmatrix} 12 & 6 \\ 4 & 8 \end{bmatrix} \]
1. Find \( CD \)
2. Find \( DC \)
---
**Case III:**
\[ E = \begin{bmatrix} 2 & 5 \\ x & \frac{1}{4} \end{bmatrix} \]
Find \( x \) such that the determinant equals \(-\frac{1}{2}\).
\[ F = \begin{bmatrix} \frac{7}{12} & -\frac{1}{4} \\ y & 2 \end{bmatrix} \]
Find \( y \) such that the determinant equals 20.
