    Answer                                           Answer

The LCM for 8 and 6 is 24                        The LCM for 4 and 10 is 20

??  +  ??   =  ??    +   ??      ??              ?? -     ??  =  ????  -   ????                                                 ??
??     ??      ????      ???? =  ????                     ??     ????      ???? =                                               ????
                                                 ????

    EX (3)                                                EX (4)

                     xx                                                    x

                     x      ?? = ?x?   ,                               ??  x     ????                                           ,

                            ?? ????                                        =
                                                                       ???? ????

                            So ?? + ?? =                               So ???? - ???? = ??

                                   ??4 ????                                   ???? ???? ????
