subtract (3b -2c) - (6c +2b) - (b+c)
To solve this expression:
(3b - 2c) - (6c + 2b) - (b + c)
First, distribute the negative sign to each term inside the parentheses:
3b - 2c - 6c - 2b - b - c
Next, combine like terms:
(3b - 2b - b) + (-2c - 6c - c)
Simplifying, we get:
0b - 9c
The final answer is:
-9c.
