x + y = 17
Можете взять это:
1. x = 1, y = 16
1 + 16 = 17
2. x = 2, y = 15
2 + 15 = 17
3. x = 3, y = 14
3 + 14 = 17
Вот ещё несколько вариантов:
x = 0, y = 17
0 + 17 = 17
x = 4, y = 13
4 + 13 = 17
x = 5, y = 12
5 + 12 = 17
x = 6, y = 11
6 + 11 = 17
x = 7, y = 10
7 + 10 = 17
x = 8, y = 9
8 + 9 = 17
x = 9, y = 8
9 + 8 = 17
x = 10, y = 7
10 + 7 = 17

Б) (238 145-237 776):41+327:3*7 = 772
В) 10000-120*80+(900-750:25)*7 = 6460
А) 690:3*205-47150+850=850
1) 690 : 3 = 230
2) 230 * 205 = 47150
3) 47150 - 47150 = 0
4) 0 + 850 = 850
ответ: 850
Б) (238 145-237 776):41+327:3*7 = 772
1) 238 145 - 237 776 = 369
2) 369 : 41 = 9
3) 327 : 3 = 109
4) 109 * 7 = 763
5) 763 + 9 = 772
ответ: 772
В) 10000-120*80+(900-750:25)*7 = 6460
1) 750 : 25 = 30
2) 900 - 30 = 870
3) 870 * 7 = 6090
4) 120 * 80 = 9600
5) 10000 - 9600 = 400
6) 6090 + 400= 6460
ответ: 6460
