 Sum number equals integer (Posted on 2011-06-11)
Each of the small letters in bold represents a different base x digit from 0 to x-1 to satisfy this alphametic equation. None of the numbers can contain any leading zero.

(x-1)*number = integer

Determine the minimum positive integer value of x such that the above equation has at least one solution. What is the next smallest value of x having this property?

Let z=x/2.  Then a parametric solution for all even bases starting with x=14 is:

B=z-2, E=z, G=1, I=2z-4, M=2z-2, N=2z-3, R=0, T=3, U=2z-6
`2z-4 2z-3    3  z     1 z 0+    2z-3 2z-6 2z-2 z-2 z 0---------------------------2z-3 2z-6 2z-2  z-2 z   0 0`
