|-9x-9|=18

Lösung

∣ - 9 x - 9 ∣ = 18

x = - 3 or x = 1

Schritte zur Lösung

∣ - 9 x - 9 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 9 x - 9 = - 18 or - 9 x - 9 = 18

- 9 x - 9 = - 18 or - 9 x - 9 = 18

x = - 3 or x = 1

x^{2} + 6 = 5 ∣ x ∣

3 ∣ x - 3.5 ∣ + 7.5 = 7.5

∣ d - 1 ∣ = 15

3 ∣ 3 x - 4 ∣ = 24

6 = ∣ - 2 f ∣
