Answer 1

A, 21

Explanation:

You would first need to divide 4 by 120 to get an idea on what a number plus 9 would get you.

If you divide 4 by 120, it'll be 30. So thats what the answer would be when the number is added to 9.

Now that we have 30, we can subtract 9 by it which will give you 21.

When you double check, 9+21=30, 30 x 4=120.

Answer 2

the number is 21

Explanation:

(9+x)(4)=120

9+x=30

x=21
