(3b−2c)−(6c+2b)−(b+c)

Answer 1

To simplify the expression (3b−2c)−(6c+2b)−(b+c), we can remove the parentheses and combine like terms.

First, distribute the negative sign in front of the second and third parentheses:

(3b−2c)−6c−2b−b−c

Now, combine like terms:

3b − 2c − 2b − b − c − 6c

Combine the b terms: (3b − 2b − b) = 0b = 0

Combine the c terms: (-2c - c - 6c) = -9c

So the simplified expression is: -9c
