To solve this problem, we can use algebra. Let's call the number we're trying to find "x".
The difference between a number (x) and 7 can be expressed as (x - 7).
Four times this difference can be written as 4(x - 7).
We are told that this expression is equal to 12, so we can set up the equation:
4(x - 7) = 12
Now, we can solve for x:
4x - 28 = 12
Adding 28 to both sides:
4x = 40
Dividing both sides by 4:
x = 10
Therefore, the number we're looking for is 10.
