CJM:

Joel & Ramah have the same amount of money. After Ramah gave $52 to Joel, Joel had twice as much as Ramah. How much money did each of them have at first.

In the end:

Joel = 2x
Ramah = x

Before the transfer:

Joel = 2x - $52
Ramah = x + $52

2x - $52 = x + $52

2x = x + $104
therefore: x = $104

So, in the beginning: they each had: $104 + $52 = $156

Hope that helped

Hi Tianzhu,
Your solution is so beautifully done. Not just mathematically but also artistically. May I know how did you so that?!
