notam paranteza cu o litera si rezolvam

426-b=366

b=426-366=60 rezultatul parantezei                          460-10xa=60

                                                                                     notam 10xa cu olitera

                                                                                 460-c=60

                                                                                 c= 460-60=400

10xa=400

a=400:10=40                             a=40
