2,1=1,8*(-2)+i⇒i=2,1+3,6=5,7
2=1,8*(-2)+i⇒i=2+3,6=5,6
1=1,8*(-2)+i⇒i=1+3,6=4,6

SergFlint: В условии написано i=2, 1 (двойка отделена от 1 пробелом). Поэтому не совсем понятно, то ли дано одно значение i=2,1, то ли два значения: i=2 и i=1. Отвечающий на всякий случай рассмотрел все три варианта, и при этом нигде не ошибся. Ответ принят.
