213*(Х-89)=9585                     4848:(60-Х)=101
Х-89=9585:213                        60-Х=4848:101
Х-89=45                                  60-Х=48
Х=45+89                               Х=60-48
Х=134                                     Х=12

(Х+51)*309=16686                  9435:(77-Х)=555
Х+51=16686:309                     77-Х=9435:555
Х+51=54                                 77-Х=17
Х=54-51                                  Х=77-17
Х=3                                         Х=60
