Answer 1

The Present age of Laura is x years.

Therefore, the present age of Micheal is 6x.

Answer 1 - In 15 years, Micheal's age = 6x + 15

Answer 2 - 15 years time,

6x + 15 = 3 (x + 15)

Answer 3 - Solve the above equation

6x + 15 = 3x + 45
3x = 30
x = 10 years

Therefore, Micheal' age = 6x = 6 * 10 = 60 years

The present age of Micheal is 60 years and present age of Laura is 10 years.
