Question 1000170
Kirk has 12 dollars less than Jim. If Jim spends half of his money, and Kirk spends none, then Kirk will have two dollars more than Jim. How much money did they both start with? 
--------
Equations:
k = j - 12
k = (j/2) + 2
------
Substitute and solve for "j"::
j - 12 = (j/2)+2
------
j/2 = 14
Jim = $28 (amt. Jim started with)
---
Kirk = j-12 = $14 (amt. Kirk started with)
