Answer:

Step-by-step explanation:
The equation given is:

We take d's to one side and others to another side of the equal sign. Thus,

<u>Note:</u> remembering to change signs when changing sides
Now, we want to isolate d on the RHS:

To make "d" the subject, we divide both sides by "m+6", to get our answer:

This is the answer.
