    Answer is+28

    Step-by-step explanation:

    To solve this question, we will have to do the normal calculation first by opening the bracket then it's followed by substitution

    Ok ... let's start solving

    Back to the question,

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

    Using bodmas rule

    Bracket first,

    -6x+4+x+9

    Collect like terms

    -6x+x+4+9

    -5x+13

    And in the question, it states that x=-3

    Therefore we will have to substitute the value of x into our initial answer

    -5 (-3) + 13

    Remember that - * -=+

    +15+13

    =+28
