Question 608366: The age of a woman and her daughter add up to 39years in 3years time the woman will be 4times as old as her daughter.find the ages of the woman and her daughter. Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! The age of a woman and her daughter add up to 39years
w + d = 39
:
in 3years time the woman will be 4times as old as her daughter
w + 3 = 4(d + 3)
w + 3 = 4d + 12
w = 4d + 12 - 3
w = 4d + 9
:
In the first equation, replace w with (4d+9)
4d + 9 + d = 39
4d + d = 39 - 9
You should be able to take it from here
