Найди неизвестное число. m•47+200=1328 6300-n: 12=5470 884: 26+p=1600 (1908+r): 25=80

M*47 + 200 = 1328
m*47 = 1328-200
m = 1128 : 47
m= 24
6300 - n:12 = 5470
n:12 = 6300 - 5470
n = 830*12
n= 9960
884:26 + p = 1600
p = 1600 - 884:26
p = 1566
(1908 + r) : 25 = 80
1908 + r = 80 * 25
r = 2000 - 1908
r = 92
