Mark is m years old now ,two years ago, hjs age was m-2
and at that time, his father's age was: 4(m-2)

now, 2 years later, his father age is:
4(m-2) + 2
=4m-8+2
=4m-6

Mark's age (now) = m years old
Mark's age (2 years ago) = (m-2) years old
Mark's father's age (2 years ago) = 4(m-2) years old
Mark's father's age (now) = 4(m-2)+2
= 4m-8+2
= 4m-6
= 2(2m-3) years old

Let his father is y years old

Then y = 4 x (m-2)

=4 years old.

Mark's father is 4(m-2) years old.

(m - 2) X 4years
