To subtract these expressions, we need to expand the parentheses and then combine like terms.

First, let's expand the first set of parentheses:
(3b - 2c) - (6c + 2b) - (b + c)
= 3b - 2c - 6c - 2b -b - c

Now, let's combine like terms:
= (3b - 2b - b) + (-2c - 6c - c)
= (0b - 4b) + (-9c)
= -4b - 9c

So, the final simplified expression is -4b - 9c.
