Answer 2

Solution:

Let's solve the problem step by step.

1. Let's assume the number of stamps Ivan had is represented by x. 2. Samal had 10 more stamps than Ivan, so the number of stamps Samal had is x + 10. 3. Oscar had three times the number of stamps Ivan had, so the number of stamps Oscar had is 3x.

Now, we can form an equation based on the given information: - When Samal gave 5 stamps, the total number of stamps Samal and Ivan had became 45.

We can represent this information in the form of an equation: x + (x + 10) - 5 = 45

Let's solve for x to find the number of stamps each child had.

Calculation:

x + (x + 10) - 5 = 45 2x + 5 = 45 2x = 45 - 5 2x = 40 x = 20

Now that we have found the value of x, we can find the number of stamps each child had: - Ivan: x = 20 - Samal: x + 10 = 30 - Oscar: 3x = 60

So, the number of stamps each child had is: - Ivan: 20 stamps - Samal: 30 stamps - Oscar: 60 stamps
