第一题翻译：在一个盒子里有48罐牛奶，在另一个相似的盒子里有33罐牛奶。第一个盒子重15千克而第二个盒子重10千克600克（或者说10.6千克）。算出当两个盒子空了时候它们的总重量。
解答：设盒子重量为X，每罐牛奶重量为Y
则由题意有：48Y+X=15
33Y+X=10.6
解得：X=23/25 （千克）
Y=22/75 （千克）
所以两个盒子空的时候的总重量为2X，即为46/25千克，即1.84千克。
第二题
解答：
设椅子（chair）有X个，凳子（stool）有Y个
由题意有： 4X+3Y=39
由于X,Y一定为整数，
所以可得出以下几种情况：
1, X=0,Y=13
2， X=3,Y=9
3, X=6,Y=5
4, X=9,Y=1
呵呵，终于写完了，希望对你有所帮助。
