Question 857338: a man is five year older than his wife and 7 times as old as his son when the son was born the age of the wife was five all over six hats of husbands age.find their ages?
You can put this solution on YOUR website! Let their present ages be m, w, s
write an equation for each statement, simplify
:
a man is five year older than his wife
m = w + 5
and 7 time older than his son
m = 7s
when the son was born, the age of the wife was that of the husbands age.
subtract the son's age from both
w - s = (m - s)
replace m with 7s
w - s = (7s-s)
w - s = (6s)
Cancel 6
w - s = 5s
w = 5s + s
w = 6s
In the first equation m = w + 5
replace m with 7s, replace w with 6s
7s = 6s + 5
7s - 6s = 5
s = 5 yrs is the son's age:
I'll let you find the man and the wife's ages
