The quotient of 8 and the sum of twice the number and 7

I can't get this one, I am trying I think it to be 8/7 + 2(8/7) but the wording 'the number', because it does state 'a number' is throwing me. Also, does the word and mean plus?

It could be 8/(2x+7)

"The quotient of (this) and (that)" is (this)/(that).

"The sum of (this) and (that)" is (this) + (that).

"Twice (this)" is 2(this).

Working out from the inside, you should end up with the second version, not the first (especially since the first has no variable that would stand for "the number", being the unknown).
