To simplify the expression \((3b - 2c) - (6c + 2b) - (b + c)\), we can follow these steps:
1. Distribute the negative signs:
\[
= 3b - 2c - 6c - 2b - b - c
\]
2. Combine like terms (group \(b\) terms and \(c\) terms):
- For \(b\):
\[
3b - 2b - b = 0b = 0
\]
- For \(c\):
\[
-2c - 6c - c = -9c
\]
3. Putting it all together:
\[
0 - 9c = -9c
\]
Therefore, the simplified expression is:
\[
\boxed{-9c}
\]
