Question 931190: Four years ago a man was three times as old as his son.Five years hence,the man will be two times as old ashis son.Find their present ages. Answer by ewatrrr(24785) (Show Source):
Hi
Let x and y represent the son's and father's ages respectively
y - 4 = 3(x-4) 0r y =
......
y + 5 = 2(x+5)
(3x-8) + 5 = 2x + 10
x = 13, son's age. Father is 31
And...checking
27 = 3(9) and 36 = 2(18)
