61a−11b+50 = (61a−11b+40)+10 = 0 + 10 = 10

Ответ: 10

РЕШЕНИЕ:
3a−6b+4 = 7 (6a−3b+4)
3a−6b+4 = 42a - 21b + 28
42a - 21b + 28 - 3a + 6b - 4 = 0
39a - 15b + 24 = 0

39a−15b+25 = (39a−15b+24)+1 = 0 + 1 = 1

Ответ: 1

РЕШЕНИЕ:
a−4b+7 = 8 (4a−b+7)
a−4b+7 = 32a - 8b + 56
32a - 8b + 56 - a + 4b - 7 = 0
31a - 4b + 49 = 0

31a−4b+55 = (31a−4b+49)+6 = 0 + 6 = 6

Ответ: 6

РЕШЕНИЕ:
4a−9b+3 = 5 (9a−4b+3)
4a−9b+3 = 45a - 20b + 15
45a - 20b + 15 - 4a + 9b - 3 = 0
41a - 11b + 12 = 0

41a−11b+15 = (41a−11b+12)+3 = 0 + 3 = 3

Ответ: 3

РЕШЕНИЕ:
5a−8b+2 = 3 (8a−5b+2)
5a−8b+2 = 24a - 15b + 6
24a - 15b + 6 - 5a + 8b - 2 = 0
19a - 7b + 4 = 0

19a−7b+12 = (19a−7b+4)+8 = 0 + 8 = 8

Ответ: 8

РЕШЕНИЕ:
3a−7b+6 = 4 (7a−3b+6)
3a−7b+6 = 28a - 12b + 24
