Subtract: (3b−2c)−(2b+6c)−(b+c) (1 point)
To subtract these expressions, first distribute the negative sign to each term within the parentheses:
(3b - 2c) - (2b + 6c) - (b + c)
= 3b - 2c - 2b - 6c - b - c
Next, combine like terms by adding or subtracting coefficients of the same variable:
= (3b - 2b - b) + (-2c - 6c - c)
= (3 - 2 - 1)b + (-2 - 6 - 1)c
Simplifying further:
= 0b + (-9)c
= -9c
Therefore, the final answer is -9c.
