Edit. Removed misleading information from the original post.
I ran across this puzzle - it's part of a larger puzzle - a week ago.
There are twelve letters, each of which corresponds to one of eight digits.
The letters are juxtaposed into two-digit numbers, and they occur that way in six equations.
Here are the equations - six, in twelve unknowns.
Their integer properties provide additional constraints.
VG = CV - QP
JY = GP - ZY
QG = VJ - MV
XC = BC - XP
XK = KX - QB
ZP = CY - GM
Can you find consistent values of the 12 letters B C G J K M P Q V X Y Z
using just eight digits?
