Answer:

8C+5D+9

Step-by-step explanation:

You can only add the same value together.

7+D+8C+4D+2

There are no other C's, so we keep it as apart of the answer; 8C.

7+D+8C+4D+2

They have the same values. So first we count D as 1D. Then we add D+4D=5D.

7+D+8C+4D+2

There are no more values left so now we add the whole numbers. 7+2=8.

Now all the problem is done. We put them in alphabetical order with the whole number being last.

8C+5D+9

Hope this helped! If you want me to go in more detail or have any questions, please ask. :)

Hope you have a nice day!
