    Answer:

     - x - 3

    Step-by-step explanation:

    1) regroup term.

     -  \frac{1}{2} (8x - 4) + 3x - 5

    2) Simplify 1/2 ( 8x – 4 ) to 8x – 4/2.

     -  \frac{8x - 4}{2}  + 3x - 5

    3) Factor out the common term 4.

     -  \frac{4(2x - 1)}{2}  + 3x - 5

    4) Simplify 4( 2x – 1 ) / 2 to 2( 2x – 1).

     - 2(2x - 1) + 3x - 5

    5) Expand by distributing terms.

     - (4x - 2) + 3x - 5

    6) Remove parentheses.

     - 4x + 2 + 3x - 5

    6) Collect like terms.

    ( - 4x + 3x) + (2 - 5)

    8) Simplify.

     - x - 3

    Therefor, the answer is -x 3.
