### Evaluating Triple Integrals

To evaluate the triple integral \(\iiint_E f(x, y, z) \, dV\) as an iterated integral for the given function \(f\) and the solid region \(E\): 

#### Functions and Regions

1. **Function 5: \(f(x, y, z) = x\)**
   - Region \(E\) is defined by:
     - **Bounds**: 
       - \(z = 1 - x^2\)
       - \(y + z = 2\)
   - **Diagram**: Displays a region in a 3D space enclosed between the given surfaces.

2. **Function 6: \(f(x, y, z) = xy\)**
   - Region \(E\) is defined by:
     - **Bounds**: 
       - \(z = 4 - y^2\)
       - \(y = x\)
   - **Diagram**: Illustrates another solid region where the boundaries form a curved shape in a 3-dimensional coordinate system.

#### Coordinate Transformation

Use the transformation \(u = x + y\), \(v = x - y\) to set up the iterated integral 

\[
\iint_R \frac{x-y}{x+y} \, dA
\]

- **Region \(R\)** has vertices at:
  - \((0, 2)\)
  - \((1, 1)\)
  - \((2, 2)\)
  - \((1, 3)\)

These transformations and expressions are used to simplify the integrals over the region \(R\) using the new coordinates \((u, v)\).
