[tex]-(7,35-32,35)-8,44=16,56\\-7,35+32,35-8,44=16,56\\25-8,44=16,56\\16,56=16,56[/tex]

Ответ:

[tex]\bf x = - 32,35[/tex]

Пошаговое объяснение:

[tex]\sf - (7,35 + x) - 8,44 = 16,56 \\ \\ \sf - 7,35 - x - 8,44 = 16,56 \\ \\ \sf - x = 16,56 + 15,79 \\ \\ \sf - x = 32,35 \\ \\ \bf x = - 32,35[/tex]

Проверка:

[tex]\sf - \Big(7,35 + (-32,35)\Big) - 8,44 = 16,56 \\ \\ \sf - (7,35 - 32,35) - 8,44 = 16,56 \\ \\ \sf - 7,35 + 32,35 - 8,44 = 16,56 \\ \\ \sf -15,79+32,35 = 16,56 \\ \\ \underline{\sf 16,56 = 16,56}[/tex]
