x = - 24 or x = 10

Schritte zur Lösung

∣ x + 7 ∣ = 17

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 7 = - 17 or x + 7 = 17

x + 7 = - 17 or x + 7 = 17

x = - 24 or x = 10

∣ x + 7 ∣ = 16

- 2 = ∣ 2 w - 4 ∣ - 9

∣ 2 (1 + x) - 3 ∣ = (0.4 x - 3)

- 8 ∣ g ∣ - 8 = - 2

∣ x + 7 ∣ = 52
