Schritte zur Lösung

∣ 8 - 9 x ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

8 - 9 x = - 8 or 8 - 9 x = 8

8 - 9 x = - 8 or 8 - 9 x = 8

x = 0 or x = \frac{16}{9}

\frac{- 3}{1 - x} < 7

3 + 5 x = 23

f a c t or k^{2} - 8 k

- 23 \leq 4 x - 11 \leq 1

4 d - 4 = 5 d - 8
