\[1)\ 0,3m + 2 \cdot (0,2m - 0,3) =\]
\[= 0,8 - 0,7 \cdot (m - 2)\]
\[0,3m + 0,4m - 0,6 =\]
\[= 0,8 - 0,7m + 1,4\]
\[0,7m + 0,7m = 2,2 + 0,6\]
\[1,4m = 2,8\]
\[m = 2\]
\[Ответ:2.\]
\[2)\ 0,6 - (1,3x + 1) =\]
\[= 2,8x - 13,52\]
\[0,6 - 1,3x - 1 = 2,8x - 13,52\]
\[2,8x + 1,3x = - 0,4 + 13,52\]
\[4,1x = 13,12\]
\[x = 3,2\]
\[Ответ:3,2.\]
\[3)\frac{1}{8} \cdot \left( \frac{8}{9}y + 8 \right) -\]
\[- \frac{1}{5} \cdot \left( \frac{5}{6}y + 1\frac{2}{3} \right) = 2\]
\[\frac{1 \cdot 8}{8 \cdot 9}y + \frac{1 \cdot 8}{8 \cdot 1} - \frac{1 \cdot 5}{5 \cdot 6}y -\]
\[- \frac{1 \cdot 5}{5 \cdot 3} = 2\]
\[\frac{1}{9}y + 1 - \frac{1}{6}y - \frac{1}{3} = 2\]
\[\frac{2 - 3}{18}y = 2 - 1 + \frac{1}{3}\]
\[- \frac{1}{18}y = 1\frac{1}{3}\]
\[y = - 24\]
\[Ответ:\ - 24.\]
