Answer 2

Calculating the Age Difference and Age of Nastya

To calculate the age difference between Lisa and Nastya, and Nastya's current age, we can use the information provided.

- Lisa is 8 years older than Nastya. - Two years ago, Lisa was three times as old as Nastya.

Let's calculate Nastya's current age and the age difference between Lisa and Nastya.

Step 1: Let's assume Nastya's current age is represented by "N" and Lisa's current age is represented by "L".

Step 2: We can set up the following equations based on the given information: - L = N + 8 (Lisa is 8 years older than Nastya) - (L - 2) = 3 * (N - 2) (Two years ago, Lisa was three times as old as Nastya)

Step 3: Solve the equations to find Nastya's current age and the age difference.

Using the given information, we can solve for Nastya's current age and the age difference between Lisa and Nastya.

Nastya's Current Age: - Using the equation L = N + 8, we can substitute L with (N + 8) in the second equation: - ((N + 8) - 2) = 3 * (N - 2) - N + 6 = 3N - 6 - 12 = 2N - N = 6

Age Difference: - Lisa is 8 years older than Nastya, so Lisa's current age (L) can be calculated as: - L = N + 8 - L = 6 + 8 - L = 14

Therefore, Nastya is currently 6 years old, and Lisa is 14 years old.

Conclusion

Nastya is currently 6 years old, and Lisa is 14 years old.
