Answer:
Explanation:
To simplify the expression 3a + 4b + 5c + (-2a) + b, we can combine like terms by adding the coefficients of the same variables.
Grouping the terms with the same variables together, we have:
(3a + (-2a)) + 4b + b + 5c
Combining the like terms:
(3a - 2a) + 4b + b + 5c = a + 5b + 5c
Therefore, the simplified form of the expression 3a + 4b + 5c + (-2a) + b is a + 5b + 5c.
