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

1 answer

To subtract the given expressions, we need to distribute the negative signs for the second and third sets of parentheses and then combine like terms. Let's proceed step by step:

Initial expression:
(3b - 2c) - (6c + 2b) - (b + c)

Distribute negative signs:
(3b - 2c) - 6c - 2b - b - c

Combine like terms:
(3b - 2b - b) + (-2c - 6c - c)

Combine b terms:
3b - 2b is b, and b - b is 0b (which is simply 0; thus, the b terms cancel out).

Combine c terms:
-2c - 6c is -8c, and -8c - c is -9c.

Therefore, after combining like terms, the result is:
0b - 9c

Since 0b is just 0, we can write the final result as:
-9c
