To simplify the expression \(-3a + 4 + 5a - 7 + a\), we will combine the like terms. 1. Combine the terms with \(a\): \(-3a + 5a + a = (5a - 3a + 1a) = 3a\) 2. Combine the constant terms: \(4 - 7 = -3\) Putting it all together, we have: \[ 3a - 3 \] So the simplified expression is \(3a - 3\).

-3a+4+5a-7+a

To simplify the expression \(-3a + 4 + 5a - 7 + a\), we will combine the like terms.

Combine the terms with \(a\): \(-3a + 5a + a = (5a - 3a + 1a) = 3a\)
Combine the constant terms: \(4 - 7 = -3\)

Putting it all together, we have:

\[ 3a - 3 \]

So the simplified expression is \(3a - 3\).
