Lösung

∣ 2 a - 15 ∣ = 77

a = - 31 or a = 46

Schritte zur Lösung

∣ 2 a - 15 ∣ = 77

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 a - 15 = - 77 or 2 a - 15 = 77

2 a - 15 = - 77 or 2 a - 15 = 77

a = - 31 or a = 46

(x - 2)^{2} + ∣ x - 2 ∣ - 2 = 0

- 2 ∣ x + 3 ∣ - 4 = - 8

∣ - x + 3 ∣ = 8

∣ 6 x + 1 ∣ = - 7

- 8 ∣ 10 n - 5 ∣ = - 120
