There are two long and short candles. The sum of their lengths is 56 cm. In the same time, the two candles burn for the same length. Now after lighting them simultaneously for a period of time, the remaining length of the short candle is exactly (2/3) of the remaining length of the long candle, and at this time the remaining length of the long candle is as long as the short candle before lighting. How long is the long candle in cm before it is lit?
有长短两支蜡烛，他们的长度之和是56cm，在相同时间内，两支蜡烛燃烧的长度相同．现在将它们同时点燃一段时间后，短蜡烛剩下的长度恰好是长蜡烛剩下长度的(2/3)，而这时长蜡烛剩下的长度与点燃前的短蜡烛一样长．点燃前，长蜡烛长多少cm．
