Problem Analysis

Vasyl initially made several paper models of airplanes and ships. After giving away 5 airplane models and 9 ship models, he was left with 8 models. We need to determine the total number of models Vasyl made.

Solution

Let's assume the total number of models Vasyl made is 'x'. After giving away 5 airplane models and 9 ship models, he was left with 8 models. We can represent this information in the following equation:

x - 5 - 9 = 8

Simplifying the equation, we have:

x - 14 = 8

Adding 14 to both sides of the equation, we get:

x = 8 + 14

x = 22

Therefore, Vasyl made a total of 22 models.

Answer

Vasyl made a total of 22 models.
