Tim is 20 years older than Don. In 8 years. Tim will be 3 times as old as Don. How old are they now?
-------
Equations:
t = d + 20
t+8 = 3(d+8)
------
Substitute for "t" and solve for "d":
d+20 + 8 = 3d + 24
-----
2d = 4
d = 2 yrs (Don's age now)
-----
Solve for "t":
t = d + 20
t = 22 yrs (Tim's age now)
