magic square
HI
I need some help.
In a square 3 x 3 using the numbers 1 to 9 once only put the numbers so that:
the numbers on the top row minus the numbers in the 2nd row = the numbers on the 3rd row.

trying this for about 4 hrs and am always 1 number out..thanks in advance

It might not even be possible (or do you know for sure that it is?)

Yes, my brute-force computer program shows that this is not possible.

Definitely no solution...
Unless he means:
459
173
286

459 - 173 = 286

BUT there's 336 solutions of that style!
