John is 4 times as old as Martha. Five years ago the sum of their ages was 50. How old are they now?

hm..
40 divide by 10.
therefore, john is 40 and Martha is 10
That sounds about right. :) Thank you. <3
What about "Five years ago the sum of their ages was 50." ?

35 + 5 does not equal 50
That would mean we would have to add 5 to each age to get the ages that the two people are at now, wouldn't it?
Ok try that.
*nods*
its easy get John's age as x and Martha's age as y Then x=4y sum of ages before 5 years was 50 So now it is 60 x + y = 60 Solving 5y = 60 y = 12 x =48
