Решите уравнения надо ! а) 11 3/4 - х = 10 5/6 б) y - 5 5/6 = 3 3/4 в)8 - y = 4 1/7 г) 4 3/8 + x = 6 1/8

а) 11 3/4 - х = 10 5/6                   б) у - 5 5/6 = 3 3/4

х = 11 3/4 - 10 5/6                        у = 3 3/4 + 5 5/6

х = 11 9/12 - 10 10/12                  у = 3 9/12 + 5 10/12

х = 10 21/12 - 10 10/12                у = 8 19/12

х = 11/12                                       у = 9 7/12

в) 8 - у = 4 1/7                              г) 4 3/8 + х = 6 1/8

у = 8 - 4 1/7                                  х = 6 1/8 - 4 3/8

у = 7 7/7 - 4 1/7                            х = 5 9/8 - 4 3/8

у = 3 6/7                                       х = 1 6/8

                                                     х = 1 3/4
