Schritte zur Lösung

∣ 9 x - 10 ∣ = 17

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

9 x - 10 = - 17 or 9 x - 10 = 17

9 x - 10 = - 17 or 9 x - 10 = 17

x = - \frac{7}{9} or x = 3

- 6 + 6 ∣ x - 6 ∣ = - 36

\frac{y}{2} = 11

∣ 0.127 x + 9 ∣ = x^{2} - 2

∣ x + 7.5 ∣ = - 2

∣ x + 1 ∣ = x^{2} + x
