subtract (3b-2c) - (6c+2b) - (b+c)
To subtract the given expression:
(3b - 2c) - (6c + 2b) - (b + c)
First, distribute the negative sign to each term inside the second parentheses:
3b - 2c - 6c - 2b - b - c
Combine like terms:
(3b - 2b - b) + (-2c - 6c - c)
Simplifying further:
0b - 9c
Therefore, the simplified expression is -9c.
