Answer:
The numbers are approximately: 4.000 and 1.000
Step-by-step explanation:
The given parameters can be expressed as:


Required
Determine the numbers
In each of the equations, multiply by 1000
![1000 * [\frac{x}{1000} + \frac{y}{1000} \approx 5]](https://tex.z-dn.net/?f=1000%20%2A%20%5B%5Cfrac%7Bx%7D%7B1000%7D%20%2B%20%5Cfrac%7By%7D%7B1000%7D%20%5Capprox%205%5D)

![1000 * [\frac{x}{1000} - \frac{y}{1000} \approx 3]](https://tex.z-dn.net/?f=1000%20%2A%20%5B%5Cfrac%7Bx%7D%7B1000%7D%20-%20%5Cfrac%7By%7D%7B1000%7D%20%5Capprox%203%5D)

So, we have:


Add the two equations


Solve for x


Substitute
in 



Using:

We have:


<em>This implies that, the numbers approximates to 4.000 and 1.000, respectively.</em>
