Answer:
18
Explanation:
We can put this into "equation" terms to make it easy for us to solve for the number. Let's assign the "number" the variable x.
The sum of 4 and 7 times a number is 7x + 4. All of this is 130 which means it's equal to 130. So below is how it looks like:
7x + 4 = 130
7x = 126
x = 18
The number therefore is 18
