2) 320:(52-X)=8
3) 50*У-72=78

Answer 1

1) 16+48:Z=40                   2) 320:(52-X)=8                3) 50*У-72=78
       48:z=40-16                     52-x=320:8                         50y=78+72
        48:z=24                         52-x=40                               50y=150
         z=48:24                        x=52-40                                y=150:50
          z=2                               x=12                                       y=3
