\[\boxed{\text{92\ (92).\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
\[1)\ 1 - 4 \cdot (x + 1) = 1,8 - 1,6x\]
\[1 - 4x - 4 = 1,8 - 1,6x\]
\[- 4x + 1,6x = 1,8 - 1 + 4\]
\[- 2,4x = 4,8\]
\[x = - \frac{4,8}{2,4}\]
\[x = - 2\]
\[Ответ:\ x = - 2.\]
\[2)\ 3 \cdot (0,5x - 4) + 8,5x =\]
\[= 10x - 11\]
\[1,5x - 12 + 8,5x = 10x - 11\]
\[1,5x + 8,5x - 10x = 12 - 11\]
\[10x - 10x = 1\]
\(0 \cdot x = 1\)
\[Ответ:корней\ нет.\]
