Об'ясните

1)

\[2x-\frac{3}{5}x=1\frac{1}{2}-\frac{1}{2}x-\frac{1}{2}-\frac{2}{5}x+2\]

Соберём подобные слагаемые:

\[\frac{7}{5}x=3-\frac{9}{10}x\]

\[\frac{23}{10}x=3\]

\[x=\frac{30}{23}\]

2)

\[x+1\frac{1}{2}x+9=\frac{2}{3}x+4+\frac{5}{6}x-1\frac{1}{5}x+\frac{1}{5}\]

\[\frac{5}{2}x+9=\frac{3}{10}x+\frac{21}{5}\]

\[\frac{11}{5}x=-\frac{24}{5}\]

\[x=-\frac{24}{11}\]

3)

\[2\frac{1}{3}x-3\frac{1}{2}x+1=x-5\frac{1}{3}x+3\frac{1}{5}\]

\[-\frac{7}{6}x+1=-\frac{13}{3}x+\frac{16}{5}\]

\[\frac{19}{6}x=\frac{11}{5}\]

\[x=\frac{66}{95}\]
