Řeš v ℝ soustavy nerovnic:
\large - 2 \lt- x + \Large \frac{2}{3}\large \le 2\left( {x + 1} \right)
\large K = \left \langle - \Large \frac{3}{9}\large ;{\Large \frac{8}{3}\large } \right)
\large K = \left \langle - \Large \frac{5}{9}\large ;{\Large \frac{8}{3}\large } \right)
\large K = \left \langle - \Large \frac{4}{9}\large ;{\Large \frac{8}{3}\large } \right)
\large K = \left \langle - \Large \frac{4}{9}\large ;{\Large \frac{7}{3}\large } \right)
