Answer 2

Calculating Sonya's Age

To find out Sonya's age, we can use the information provided about Lisa's age. According to the information given, Lisa is 9 years old and she is 2 times younger than Sonya.

Step 1: Let's denote Sonya's age as S and Lisa's age as L. We know that Lisa is 2 times younger than Sonya, so we can express Lisa's age in terms of Sonya's age as: L = S - 2.

Step 2: Given that Lisa is 9 years old, we can substitute this value into the equation: 9 = S - 2.

Step 3: Solving for Sonya's age, we get: S = 9 + 2.

Step 4: Therefore, Sonya is 11 years old.

Conclusion

Sonya is 11 years old.
