Molly is 20 years older than Sal. in three years Molly will be twice as old as Sal how old are they now?
--------
Equations::
M = S + 20
M+3 = 2(S+3)
------
Substitute for "M" and solve for "S"::
S+20+3 = 2S+6
---
Sally = 17 yrs (Sally's age now)
-------
Solve for "M"::
M = S + 20
Molly = 17+20 = 37 yrs (Molly's age now)
