Question 863996
The sum of Tim's and Tom's ages is 63 years. At present Tim is twice as old as Tom was when Tim was as old as Tom is now. How old are Tim and Tom now?
***
let x=Tim's age now
let y=Tom's age now
y=63-x
x-y=difference in ages
x=2(y-(x-y))=2(2y-x)
x=4y-2x
3x=4y=4(63-x)
3x=252-4x
7x=252
x=36
y=63-x=27
Tim's age now=36
Tom's age now=27
