**Title: Evaluating an Integral Using a Given Transformation**

**Objective:**
To evaluate the integral using the given transformation for a specified parallelogram.

**Problem Statement:**
Evaluate the integral:
\[ \iint_R (10x + 15y) \, dA, \]
where \( R \) is the parallelogram with vertices \((-3, -12), (3, -12), (5, -10), \text{ and } (-1, -10)\).

**Given Transformation:**
\[
x = \frac{1}{2} (u + v), \quad y = \frac{1}{2} (v - 4u)
\]

**Solution Approach:**
- Use the provided transformation to express \( x \) and \( y \) in terms of new variables \( u \) and \( v \).
- Substitute these expressions into the integral.
- Evaluate the transformed integral over the new region defined by these variables.

**Additional Features:**
- A clickable button labeled "Read It"
- An option labeled "Need Help?" for further assistance.
- A "Show My Work" feature for detailed step-by-step solutions.
- Temperature display at the bottom right: 40°F, Sunny.

**Conclusion:**
This exercise provides a practical example of using transformations to simplify and solve integrals over complex geometric regions like parallelograms.
