**Damon**, Sunday, October 26, 2008 at 4:45pm(A-x)3 =B+x

3A - 3 x = B + x

4 x = 3A-B

(B - x)2 = A + x

2 B - 2x = A + x

3x = 2 B - A

12 x = 9 A - 3 B

12 x = 8 B - 4 A

---------------

0 = 13 A - 11 B

11 B = 13 A

a solution is

A = 11 and B = 13

then remember

3x = 2 B - A

3 x = 26 - 11 = 15

x = 5

multiples of those will also work though

like

A =22, B =26, x = 10
