Ответ: 1.

Пошаговое объяснение:

73x+(-1/3) = -12x + 84 2/3 => переносим члены уравнения с переменной "х" в левую часть, без - в правую? при этом меняем знаки на противоположный =>

73x+12x = 84 2/3 - (-1/3) => выполняем алгебраическое сложение =>

85x = 84 3/3=> так как 3/3 = 1, то = 84 3/3 = 85;

x=85 : 85;

x=1.
