1. The problem is to find the number that must be added to a given number to get 14000. 2. Let the number you have be $x$ and the number to add be $y$. 3. The equation is $x + y = 14000$. 4. To find $y$, rearrange the equation: $$y = 14000 - x$$. 5. This means you subtract the number you have from 14000 to find the number you need to add. 6. For example, if you have 8000, then $$y = 14000 - 8000 = 6000$$. 7. So, you need to add 6000 to 8000 to get 14000. 8. This method works for any value of $x$ you start with.
