Question

Which equation represents this sentence?

Three less than the product of seven and a number is four more than the number.



3−7n+4=n

7n−3=n+4

7n−3+4=n

3−7n=n+4

Answer 1

It's the second equation. 

Answer 2

B.
`7n-3=n+4`

Explanation:

Let n represent the number.

We are asked to write an equation for the given verbal phrase.

The product of seven and a number would be
`7n`.

Three less than the product of seven and a number would be
`7n-3`.

Four more than the number would be
`n+4`.

Equate both expressions:

`7n-3=n+4`

Therefore, our required equation would be
`7n-3=n+4`.
