Answer 2

Problem Analysis

We are given that in 6 years, Ivan (Vanya) will be twice as old as he is now. We need to determine how old Ivan was 2 years ago.

Solution

Let's assume Ivan's current age is represented by x. According to the given information, in 6 years, Ivan will be twice as old as he is now. This can be represented as:

x + 6 = 2x

To find Ivan's age 2 years ago, we need to subtract 2 from his current age:

x - 2

To solve for x, we can rearrange the equation:

x + 6 = 2x

2x - x = 6

x = 6

Now that we know Ivan's current age is 6, we can substitute this value into the equation to find his age 2 years ago:

6 - 2 = 4

Therefore, Ivan was 4 years old 2 years ago.

Answer

Ivan was 4 years old 2 years ago.

Explanation

Given that in 6 years, Ivan will be twice as old as he is now, we can set up the equation x + 6 = 2x, where x represents Ivan's current age. Solving this equation, we find that Ivan's current age is 6. Subtracting 2 from his current age, we find that Ivan was 4 years old 2 years ago.
