    Diminished is just a fancy way of saying subtract, so you can do the problem the same way as the last one.

    With this problem, make sure you only subtract like terms.

    a-a=? -2b-(-2b)=? 3c-(-3c)=? 0-d=?

    The b would cancel out because it would become -2b+2b=0. You can add the c together, though. It would be 3c+3c=6

    And 6c for the earlier one, sorry. Your final answer should be 6c-d
