Решаем уравнения:
1) n : 17 = 4556 + 2445
n : 17 = 7001
n = 7001 * 17
n = 119017
2) m : 29 = 3477 - 2963
m : 29 = 514
m = 514 * 29
m = 14806
3) 140895 : (z - 197) = 595
z - 197 = 140895 : 595
z - 197 = 236.8
z = 236.8 + 197
z = 433.8
4) (2747 + x) * 125 = 595
2747 + x = 595 : 125
2747 + x = 4.76
x = 4.76 - 2747
x = -2742.24
