Answer 1

variante: x=1 y=7 , 
               x=2 y=6
               x=3 y=5
              
               x=5 y=3
               x=6 y= 2
               x=7 y=1
               x=8 y=0

deci nr poate fi : 1700,1722,1733,1744,1755,1766,1788,1799,2600,2611,2633,2644,2655,2677,2688,2699,3500,3511,3522,3544,3566,3577,3588,3599,5300,5311,5322,5344,5366,5377,5388,5399,6200,6211,6233,6244,6255,6277,6288,6299,7100,7122,7133,7144,7155,7166,7188,7199,8011,8022,8033,8044,8055,8066,8077,8099.
