Answer 3

Problem Analysis

We are given that a boy will be twice as old in 2 years as he was 2 years ago. We need to determine the boy's current age.

Solution

Let's assume the boy's current age is x years.

According to the problem, in 2 years, the boy will be twice as old as he was 2 years ago. Mathematically, we can represent this as:

x + 2 = 2(x - 2)

Simplifying the equation:

x + 2 = 2x - 4

Bringing the x terms to one side:

x - 2x = -4 - 2

Simplifying further:

-x = -6

Multiplying both sides by -1 to isolate x:

x = 6

Therefore, the boy is currently 6 years old.

Conclusion

Based on the given information, the boy is currently 6 years old.
