Problem Analysis

We are given the following information: - The mother's age is 2 years more than three times the daughter's age. - Five years ago, the mother's age was 9 years more than nine times the daughter's age.

We need to determine the ages of the mother and the daughter.

Solution

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

According to the given information, the mother's age is 2 years more than three times the daughter's age. Therefore, the mother's current age is 3x + 2 years.

Five years ago, the mother's age was 9 years more than nine times the daughter's age. So, five years ago, the mother's age was 9(x - 5) + 9 years.

Now, we can set up an equation using the given information:

9(x - 5) + 9 = 3x + 2

Let's solve this equation to find the value of x.

9x - 45 + 9 = 3x + 2

9x + 9 = 3x + 2

9x - 3x = 2 - 9

6x = -7

x = -7/6

The value of x is negative, which doesn't make sense in the context of age. Therefore, there seems to be an error in the given information or the problem statement.

Unfortunately, I couldn't find any additional information or sources to verify or correct the given information. Please double-check the problem statement or provide any additional information if available.
