### Using Green's Theorem for Line Integrals

#### Task:
Apply Green’s Theorem to evaluate the line integral:

\[
\oint_C (y - x) \, dx + (2x - y) \, dy
\]

for the specified path \( C \).

#### Description of Path \( C \):
- The path \( C \) is described as the boundary of the region lying:
  - Inside the semicircle \( y = \sqrt{49 - x^2} \) 
  - Outside the semicircle \( y = \sqrt{25 - x^2} \)

This involves evaluating the line integral over a closed path \( C \) that is bounded by these semicircles, using Green’s Theorem to transform the line integral into a double integral over the region enclosed by \( C \).
