Ответ:

1. \(\frac{x}{3}\) ≤ \(\frac{x-3}{2}\)

   2x ≤ 3(x - 3)

   2x ≤ 3x - 9

   -x ≤ -9

   x ≥ 9

2. 3 + x ≥ \(\frac{x}{3}\)

   9 + 3x ≥ x

   2x ≥ -9

   x ≥ -4.5

3. 4 + 3x - \(\frac{x}{3}\) ≤ 1

   12 + 9x - x ≤ 3

   8x ≤ -9

   x ≤ -\(\frac{9}{8}\)

   x ≤ -1.125

4. \(\frac{2 - 3x}{4}\) ≤ \(\frac{6 - 5x}{8}\) + 0.2

   \(\frac{2 - 3x}{4}\) ≤ \(\frac{6 - 5x}{8}\) + \(\frac{1}{5}\)

   10(2 - 3x) ≤ 5(6 - 5x) + 8

   20 - 30x ≤ 30 - 25x + 8

   -5x ≤ 18

   x ≥ -3.6

5. \(\frac{2x - 1}{9}\) < \(\frac{2}{3}\) - \(\frac{x - 2}{6}\)

   2(2x - 1) < 6 - 3(x - 2)

   4x - 2 < 6 - 3x + 6

   7x < 14

   x < 2
