Fill in the boxes using each digit from 1 to 9 once so that each equation is correct. Note that all operations are performed in order from left to right or top to bottom.

  _     _     _
 |_| x |_| - |_| = 6 

  +     +     +
  _     _     _
 |_| + |_| - |_| = 5 

  -     x     /  
  _     _     _ 
 |_| x |_| / |_| = 3 

  =     =     =
  2     9     4

The solution is as follows:
 5    x    2   -    4   = 6
 +         +        +
 6    +    7  -     8   = 5
 -         x        /
 9    x    1   /    3   = 3
 =         =        =
 2         9        4
