Ответ:
422, 215.
Пошаговое объяснение:
1. 510:17+14* (48-80:4) = 30+14*(48-20) = 30+14*28= 30+392 = 422
1. 510: 17 = 30
2. 80:4 = 20
3. 48-20 = 28
4. 28*14 = 392
5. 30+392 = 422
2. 20*15+35*15-31 110:51 = 300+525-610 = 215
1. 20*15 = 300
2. 35*15 = 525
3. 31110:51 = 610
4. 300+525 = 825
5. 825 - 610 = 215
