ABCDEF*6=ABCDEF find ABCDEF if A=1.


No solution. x*6 = x only for x=0, which is impossible in your situation above.

ABCDEF*6=ABCDEF find ABCDEF if A=1.


If A=1 then ABCDEF = BCDEF

We understand the puzzle differently. I interpreted ABCDEF as representing a six-digit number, each digit represented by a letter. In that case, no solution is possible. You seem to have understood ABCDEF to mean A * BCDEF, in which case the only solution is for BCDEF to be zero.
