Пошаговое объяснение:
2)48m - 13m + 876 = 35m + 876
m = 17
35m + 876 = 35*17 + 876 = 595 + 876 = 1471
3)19x + 457 + 39x - 278 = 58x + 179
x = 13
58x + 179 = 58*13 + 179 = 754 + 179 = 933
4)75 + 36m + 27 + 64m = 102 + 100m
m = 421
102 + 100*421 = 102 + 42100 = 42202
5)35x + 204 + 66x - 199 = 101x + 5
x = 73
101*73 + 5 = 7373 + 5 = 7378
6)26a + 421 + 74a -241 = 100a + 180
a = 39
100*39 + 180 = 3900 + 180 = 4080
