![### Problem 4
**Statement:** Let \( F \) be a field. Prove or disprove the following statement: For \( a, b, c, d \in F \), we have
\[ (a + b) + 2c - d = 2c + (b - d) + a. \]
This problem requires evaluation of the given equation in the context of field properties. To determine its truth value, you can follow the properties and operations of fields, such as associativity, commutativity, and distributivity.
- **Given:** \( a, b, c, d \in F \)
- **Expression to Prove/Disprove:** \( (a + b) + 2c - d = 2c + (b - d) + a \)
You can either:
1. **Prove**: Demonstrate the equality by manipulating one side to match the other side using field properties.
2. **Disprove**: Provide a counter-example where the equality does not hold under any assignments of \( a, b, c, \) and \( d \).
Proceed accordingly by either manipulating the expressions algebraically or by trial and error with specific values.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd4a71857-d0ee-4dcb-ba99-6ef8d4931e16%2F061a047f-2984-4f05-890a-ae8652b61d97%2F4l31n0q_processed.png&w=3840&q=75)
