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?
