Answer:
Mary is 10 years old, and her father is 40 years old.
Step-by-step explanation:
Let Mary's age = x.
Mary's father is four times as old, so he is 4x.
Five years ago, Mary was x - 5, and her father was 7(x - 5).
Five years ago, Mary's father was 4x - 5.
7(x - 5) = 4x - 5
7x - 35 = 4x - 5
3x = 30
x = 10
4x = 4 * 10 = 40
Mary is 10 years old, and her father is 40 years old.
