|-2x-1|=11

Lösung

∣ - 2 x - 1 ∣ = 11

x = - 6 or x = 5

Schritte zur Lösung

∣ - 2 x - 1 ∣ = 11

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 2 x - 1 = - 11 or - 2 x - 1 = 11

- 2 x - 1 = - 11 or - 2 x - 1 = 11

x = - 6 or x = 5

∣ x - 1 ∣ = x

- 2 ∣ x - 7 ∣ = - 4

∣ 5 f - 3 ∣ = 12

∣ x + 3 ∣ = 2 x - 5

∣ 2 x - 3 ∣ = x + 4
