    The answer to your question is letter A

    Step-by-step explanation:

    Expression

    - 3x - (x - 1) + 3/2 (3x + 3)

    1. - Expand

    - 3x - x + 1 + 3/2 (3x) + 3/2 (3)

    2. - Simplify

    - 3x - x + 1 + 9/2 x + 9/2

    3. - Associate like terms

    (-3x - x + 9/2x) + (1 + 9/2)

    4. - Simplify like terms

    (-4x + 9/2x) + (2 + 9) / 2

    (-8x + 9x) / 2 + 11/2

    1/2x + 11/2
