Jim is twice as old as Karen.
j = 2k
--------------
Eight years from now, Jim will be twenty years older than Karen.
(j+8) = (k+8)+20
-----------------
How old is Jim now?
=========================
Substitute for "j" and solve for "k":
(2k+8) = k+28
---
k = 20 (Karen's age now)
----
Solve for "j":
j = 2k
j = 2*20 = 40 yrs old (Jim's age now)
============================================
