    Answer: A. 5

    Step-by-step explanation:

    First you simplify.

    3x+2-3x+7+5x

    3x and - 3x cancel each other out. In other words eliminate the opposites.

    2+7+5x

    Add like terms. 2+7=9.

    The simplified expression is 5x+9.

    A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e. g. 4 in 4x y).

    So the coefficient for the simplified expression would be 5.
