To simplify the expression 8a - 5c + b - 7a - 4c + 2b, we can combine like terms.
Combining the terms with a coefficient of "a": 8a - 7a = a.
Combining the terms with a coefficient of "c": -5c - 4c = -9c.
Combining the terms with a coefficient of "b": b + 2b = 3b.
Therefore, the expression simplifies to: a - 9c + 3b.
8a - 5c + b - 7a - 4c + 2b simplify
