Answer 1

У+74=172          2х+18=66             86+35z=331
у=172-74          2х=66-18               35z=331-86
у=98                  2х=48                    35z=245
                           х=48:2                    z=245:35
                           х=24                       z=7



2m-45=127                            (120+3p)-97=233
2m=127+45                            120+3p=233+97
2m=172                                   120+3p=330
m=172:2                                   3p=330-120
m=86                                         3p=210
                                                   p=210:3
                                                   p=70
