1) 8*17 - x = 107=> 136 - x = 107=> -x = 107 - 136=> -x = -29=> x = 29
2) 555 : 5 - x = 74=> 111 - x = 74=> -x = 74 - 111=> -x = -37=> x = 37
Поэтому, x = 29 и x = 37.
1) 8*17 - x = 107
=> 136 - x = 107
=> -x = 107 - 136
=> -x = -29
=> x = 29
2) 555 : 5 - x = 74
=> 111 - x = 74
=> -x = 74 - 111
=> -x = -37
=> x = 37
Поэтому, x = 29 и x = 37.
