messages.content: Let x be the number of nickels he is holding.
  His nickels are worth 5 * x = 5x cents.
  He has x+4 dimes.
  The dimes are worth 10 * (x+4)
  The total worth of the nickels and dimes is 5x + 10*(x+4) = 70.
  5x + 10x + 40 = 70
  15x = 30
  x = <<2=2>>2, Steve has 2 nickels in his hand.
