Fill in each of the boxes with the numbers 1 to 9 so that the three horizontal equations are true.
Each number is used once; no repetition is allowed.
The calculations are done from left to right (i.e., 72x3=15, not 1) and may involve only positive numbers (so 537=5 is not allowed).

_ _ _ _ _      x   =  
  x   x   =   +   + _ + _ +   + _
_  _ x _ = _  _  _

4 8 1 5 6 9 7 3 6
results in the bottom equation being
4  8 * 1 = 5  6  3 = 4
That's disallowed by the rule to "involve only positive numbers (so 537=5 is not allowed)."
