Explanation:

Step1: Remove parentheses

To remove the parentheses, we distribute the negative sign to the terms inside the parentheses: \(4a - (7a - 3) + 2a - 5 = 4a - 7a + 3 + 2a - 5\)

Step2: Combine like terms

First, combine the \(a\)-terms: \(4a - 7a + 2a=(4 - 7 + 2)a=-a\)
Then, combine the constant terms: \(3 - 5=-2\)
So the simplified expression is \(-a - 2\)

Answer:

\(-a - 2\)
