\[\boxed{\mathbf{1160\ (1152)}\mathbf{.}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]
\[1) - 1,4 \cdot (x - 6) =\]
\[= 7 \cdot (4x + 1,2)\]
\[- 1,4x + 8,4 = 28x + 8,4\]
\[28x + 1,4x = 8,4 - 8,4\]
\[29,4x = 0\]
\[x = 0\]
\[Ответ:0.\]
\[2)\ 2,6 \cdot (0,4x - 1,4) =\]
\[= - 3,9 \cdot (1,2x - 0,9)\]
\[1,04x - 3,64 = - 4,68x + 3,51\]
\[1,04x + 4,68x = 3,51 + 3,64\]
\[5,72x = 7,15\]
\[x = 1,25\]
\[Ответ:1,25.\]
