To simplify the expression \((x + 2) + (-x + 1)\), you can combine like terms: 1. Combine the \(x\) terms: \[ x + (-x) = 0 \] 2. Combine the constant terms: \[ 2 + 1 = 3 \] Putting it all together, the simplified expression is: \[ 0 + 3 = 3 \] Thus, \((x + 2) + (-x + 1) = 3\).

To simplify the expression \((x + 2) + (-x + 1)\), you can combine like terms:

Combine the \(x\) terms: \[ x + (-x) = 0 \]
Combine the constant terms: \[ 2 + 1 = 3 \]

Putting it all together, the simplified expression is: \[ 0 + 3 = 3 \]

Thus, \((x + 2) + (-x + 1) = 3\).
