    Algebraic equation

    4 (x + 3) + 5 (x - 4) - just for the sake of the add/subtract sign. I can't remember

    Are you looking to expand this equation like so?


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

     4 x + 12 + 5 x - 20

     9 x -8

    You called that an equation; it is not an equation, just an expression.
