The expression shown in the image is:

\[
\frac{7}{2} + \left(\frac{2}{5} - 1.5\right) - \left(-\frac{1}{2} + 3\right)
\]

### Steps to solve:

1. **Simplify the first part**:  
   \[
   \frac{7}{2} = 3.5
   \]
   
2. **Simplify inside the first set of parentheses**:  
   \[
   \frac{2}{5} - 1.5 = \frac{2}{5} - \frac{3}{2} = \frac{4}{10} - \frac{15}{10} = \frac{-11}{10} = -1.1
   \]
   
3. **Simplify inside the second set of parentheses**:  
   \[
   -\frac{1}{2} + 3 = -0.5 + 3 = 2.5
   \]
   
4. **Put everything together**:  
   \[
   3.5 + (-1.1) - 2.5
   \]
   
5. **Final calculation**:
   \[
   3.5 - 1.1 - 2.5 = 3.5 - 3.6 = -0.1
   \]

Thus, the final result is **-0.1**.
