To solve this problem, we need to determine the value of x, which represents the age difference between July and her husband.
We know that when Hannah was 6 years old, her age was double the age of July.
Therefore, July was 6/2 = 3 years old at that time.
Now, 20 years later, July is 3 + 20 = 23 years old.
We also know that July's husband is 25 years old.
To find the age difference between July and her husband, we subtract July's age from her husband's age:
x = 25 - 23
x = 2
The value of x is 2.
#### 2
The answer is: 2
