Answer:
2n ÷ 9 - x
Explanation:
The product of 2 and a number, I used "n" to replace the number. Putting a number next to a variable means multiplying.
So we have 2n and divide by the difference (subtracting) of 9 and ANOTHER number, that means we need a different variable for this I used "x".
And that's how I got 2n ÷ 9 - x as my answer.
Hope that helps and have a great day!
