Which equation represents this sentence?

Five more than three times the number is one-third more than the sum of the number and itself.

-5(3n)=1/3+n

-3n+5=1/3(n+n)

-5(3n)=1/3n+n

-3n+5=(n+n)+1/3

Assuming the bullet points are not negative signs....

Look at the first part of the phrase:

"Five more than three times the number"

The variable 'n' would represent "the number."

Three times the number would be 3n.

Five more than that would be 3n+5.

Now look at the second part of the phrase:

"one third more than the sum of the number and itself."

This is a bit tricky. (Didn't quite understand this, so I had to look at the four possible answers.)

I assume "the sum of the number and itself" is n+n.

And 1/3 more than that would simply be (n+n) + 1/3.

Now using the 'equal' sign let's put these two parts together. (No, we are not adding)

3n+5=(n+n)+1/3

And that is the fourth answer.

So the fourth answer is correct.

(This was a tricky question...especially because I spent a lot of time wondering if those bullet points were negative signs)
