Step-by-step explanation:
Part A:

<em>(I also don't know if this is the form you need it in, but I hope I could help a little.)</em>
You would add 6, so you can divide both sides by 2 later on in the equation. Since it is subtracting six on one side of the equation you need to add on the other side to cancel it out.
3/7x + 5 = 8
= 3/7x + 5 - 5 = 8 - 5
= 3/7x = 3
= (7/3) * (3/7x) = (7/3) * (3)
x = 7
