For two sections of wires of the same length, when installing an electric light, the first section uses 18 meters, and the second section uses 25 meters. The remainder of the first segment is exactly twice as long as the remainder of the second segment. How long are the two lengths of wire?
同样长的两段电线，在装电灯时，第一段用去18米，第二段用去25米．第一段余下的长度刚好是第二段余下的2倍．两段电线原来长多少米？
