Subtract: (3b−2c)−(6c+2b)−(b+c) . pls explain

1 answer

To subtract these expressions, you first need to distribute the negative sign to each term inside the parentheses.

(3b - 2c) - (6c + 2b) - (b + c) becomes:

3b - 2c - 6c - 2b - b - c

Now, combine like terms. Grouping similar terms together:

(3b - 2b) + (-6c - 2c - c) + (-b)

This simplifies to:

b - 9c - b

And finally:

- 9c
