The formula for this is:
D - 8 = 8
D - 8 + 8 = 8 + 8 (what you do to one side, you must do to the other)
D = 16
Or you can reverse it:
8 = D - 8
8 + 8 = D - 8 + 8 (again, what you do to one side, you must do to the other)
16 = D
8===d8===d8===d8===d8===d8===d8===d8===d8===d8===d8===d8===d8===d8===d8===d8===d8===d8===d

Yes. It is THE solution.
No solution
No, it is not.
No solution
8 = Pints in a Gallon
Yes.
No because x = 2
It is a basic solution
y = 6
x=14
