0 Guest Posted December 13, 2007 Report Share Posted December 13, 2007 ABCDEF*6=ABCDEF find ABCDEF if A=1. No solution. x*6 = x only for x=0, which is impossible in your situation above. Quote Link to comment Share on other sites More sharing options...
0 bonanova Posted December 14, 2007 Report Share Posted December 14, 2007 ABCDEF*6=ABCDEF find ABCDEF if A=1. If A=1 then ABCDEF = BCDEFDividing both sides by A we have BCDEF*6 = BCDEF or BCDEF=0 Thus ABCDEF = 0. This is true no matter what value A takes. If A is nonzero then BCDEF=0. If A=0 ABCDEF=0 by inspection. Quote Link to comment Share on other sites More sharing options...

If A=0 ABCDEF=0 by inspection. 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.
