You can put this solution on YOUR website! The sum of the ages of a couple is 60. In eight years, husband's age will be five years less than two times the wife's age seven years ago. Find their present ages.
--------------------
NOW DATA:
d + m = 60
---------------------
8 yrs. from now DATA:
(d+8)=2(m-7)-5
=================================
Simplify the 2nd equation:
d - 2m = -14-8-5
d-2m = -27
---------------------------------
You now have the system:
d+m = 60
d-2m=-27
--------------------------------
Subtract the 2nd from the 1st to solve for "m"
3m = 87
m = 29 yrs old (the spouse's age NOW)
-----------------------------------
Since d+m = 60 , d = 31 yrs old (the husband's age NOW)
=================================================================
