Answer 1

Answer:

12 and 42

Step-by-step explanation:

Let Mary's age be x and her daughter's age be y

Since 7 years ago Mary was 7 times older than her daughter

x - 7 = 7(y - 7) --> x - 7 = 7y - 49

3 years from now Mary will be 3 times older than her daughter

x + 3 = 3(y + 3) --> x + 3 = 3y + 9

Subtracting both equations from one another we get

-10 = 4y - 58

4y = 48

y = 12

x = 42
