помогите пожалуйста решить уравнения a) 1,4x+14=0,6x+0,4  b) 2 1/9:6 1/3=x:1,8

а) 1,4х + 14 = 0,6х + 0,4             b) 2 1/9 : 6 1/3 = х : 1,8    

1,4х - 0,6х = 0,4 - 14                       19/9 : 19/3 = х : 18/10

0,8х = - 13,6                                     19/3х = 19/9 * 18/10

х = - 13,6 : (0,8)                                19/3х = 38/10

х = 17                                                х = 38/10 : 19/3

                                                          х = 38/10 * 3/19

                                                          х = 6/10

                                                           х = 0,6
