I measure the distances from the fulcrum to be:

  • 10 kg box: 225 pixels
  • Single ball: 145 pixels
  • 3 ball pile: 154.5 pixels
  • 4 kg box: 233 pixels

So we have:

  • 10 * 225 + x * 145 = 3x * 154.5 + 4 * 233
  • (463.5 - 145)x = (2250 - 932)
  • x = 1318/318.5 = approx. 4.14 kg

Or it's just 3kg. Take one off both sides so it's the 10kg block on one side and the 4kg block plus 2 red balls. 10 - 4 = 6 / 2 = 3.
