Для начала приведем дроби к общему знаменателю, который равен 4:
8 целых 3/4 - x = 3 целых 15/16
84 + 3/4 - x = 34 + 15/16
32 + 3/4 - x = 12 + 15/16
35/4 - x = 51/16
Умножаем обе части на 16:
16(35/4) - 16x = 51
(1635)/4 - 16x = 51
560/4 - 16x = 51
140 - 16x = 51
Выразим x:
16x = 140 - 51
16x = 89
x = 89/16
Ответ: x = 89/16.
