Calculating the Number of Stamps

To determine the number of stamps Ivan has, we can use the information provided in the statement. Ivan mentioned that he has 18 stamps and "half of all my stamps."

Calculation

If we let "x" represent the total number of stamps Ivan has, we can set up the following equation: 18 + 0.5x = x

Solving for x

By solving the equation, we can find the value of x, which represents the total number of stamps Ivan has.

Solution

x = 36

Therefore, Ivan has 36 stamps in total.
