Your question seems to be about a mathematical problem. Let me try to explain it to you.

The problem is asking for the difference between the mathematical model of the problem and the actual situation after x years. The mathematical model is based on the assumption that the father's age is always 8 times the son's age. The actual situation is based on the fact that the father and the son have a total age of 45 years at the beginning.

To find the difference, we need to first find the expressions for the father's and the son's ages in both cases. Let's use F for the father's age and S for the son's age.

In the mathematical model, we have:

$$F = 8S$$

In the actual situation, we have:

$$F + S = 45$$

To find the ages after x years, we need to add x to both F and S. So we have:

In the mathematical model:

$$F + x = 8(S + x)$$

In the actual situation:

$$F + x + S + x = 45 + 2x$$

To find the difference, we need to subtract the actual situation from the mathematical model. So we have:

$$\text{Difference} = (F + x) - (F + x + S + x)$$

Simplifying, we get:

$$\text{Difference} = -S - 2x$$

Now, we need to find the value of S. We can do that by using either equation from the actual situation. Let's use the first one:

$$F + S = 45$$

Substituting F with 8S from the mathematical model, we get:

$$8S + S = 45$$

Solving for S, we get:

$$S = \frac{45}{9} = 5$$

So the son's age at the beginning is 5 years, and the father's age is 8 times that, which is 40 years.

Plugging S into the expression for the difference, we get:

$$\text{Difference} = -5 - 2x$$

This is the final answer. It means that the difference between the mathematical model and the actual situation is a linear function of x, and it is always negative. The negative sign means that the mathematical model overestimates the father's age compared to the actual situation.
