Schritte zur Lösung

\frac{7}{6} - (- \frac{2}{9})

Apply rule:

a - (- b) = a + b

\frac{7}{6} - (- \frac{2}{9}) = \frac{7}{6} + \frac{2}{9}

= \frac{7}{6} + \frac{2}{9}

\frac{7}{6} + \frac{2}{9} = \frac{25}{18}

= \frac{25}{18}

- 2 ∣ 4 - 2 x ∣ + 7 = 6

6 = 8.1 - 3 x

x (3 - x) (x - 7) < 0

x^{2} - 1 + x^{2} - 16 = 2

- 3 x^{2} + 6 x - 3 = 0
