x = - 9 or x = 2

Schritte zur Lösung

∣ 2 x + 7 ∣ = 11

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x + 7 = - 11 or 2 x + 7 = 11

2 x + 7 = - 11 or 2 x + 7 = 11

x = - 9 or x = 2

12 - 2 ∣ x - 2 ∣ = 5

13 ∣ x - 8 ∣ = 10

2 ∣ y + 2 ∣ - 8 = 0

- 3 ∣ 1 - 32 v ∣ = - 9

∣ 6 x - 10 ∣ + 10 = 48
