Question 1130157: A man is 8 years older than his wife and 6 times as old as his son. When the son was born, the age of the wife was four-fifth of her husband. Find the age of the sun now. Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! A man is 8 years older than his wife
m = w+8
or
w = m-8
and 6 times as old as his son.
m = 6s
When the son was born, the age of the wife was four-fifth of her husband.
w - s = (m-s)
get rid of the denominator, multiply by 5
5(w-s) = 4(m-s)
5w - 5s = 4m - 4s
5w = 4m - 4s + 5s
5w = 4m + s
replace w with (m-8)
5(m-8) = 4m + s
5m - 40 = 4m + s
5m - 4m = s + 40
m = s + 40
replace m with 6s
6s = s + 40
6s - s = 40
5s = 40
s = 40/5
s = 8

They say 4.6 billion years, but you probably meant the "son"

Check this, man is 48, wife is 40
"When the son was born, the age of the wife was four-fifth of her husband. "
40 - 8 = (48-8)
32 = (40)
