1) (m - 4789) + 89 = 6004
m - 4789 = 6004 - 89
m - 4789 = 5915
m = 5915 + 4789
m = 10704
(10704 - 4789) + 89 = 6004
6004 = 6004
ответ: m = 10704.
2732 + (5000 - n) = 4803
5000 - n = 4803 - 2732
5000 - n = 2071
n = 5000 - 2071
n = 2929
2732 + (5000 - 2929) = 4803
4803 = 4803
ответ: n = 2929.
(p + 7245) - 3834 = 6357
р + 7245 = 6357 + 3834
р + 7245 = 10191
р = 10191 - 7245
р = 2946
(2946 + 7245) - 3834 = 6357
6357 = 6357
ответ: р = 2946.
8113 - (10101 - r) = 5207
10101 - r = 8113 - 5207
10101 - r = 2906
r = 10101 - 2906
r = 7195
8113 - (10101 - 7195) = 5207
5207 = 5207
ответ: r = 7195.
