• 4 canaries, 3 cages.
  
  let number of canaries be x
  number of cages be y
  
  first condition: If you put in one canary per cage, you have one canary too many.
  => x= y+1
  second condition : If you put in two canaries per cage, you have one cage too many.
  => y = x/2 + 1
  => x = 2y - 2
  
  Subtracting first from second :
  0 = y-3
  =>y=3
  substitute in eq. 1 => x=4
