    The answer is 40a+14c

    Step-by-step explanation:

    Step 1: Open the brackets

    7a-9c+12a+33c+21a-10c

    Step 2: Group all the like terms

    Like terms are terms with similar variables, for example;

    (7a, 12a, 21a) are all like terms since they have a common variable (a)

    (-9c, 33c,-10c) are also like terms since they have a common variable (c)

    Step 2: Solve

    (7a+12a+21a) + (33c-10c-9c) = 40a+14c

    The answer is 40a+14c
