a = - 11 or a = 13

Schritte zur Lösung

∣ a - 1 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

a - 1 = - 12 or a - 1 = 12

a - 1 = - 12 or a - 1 = 12

a = - 11 or a = 13

- ∣ 3 x + 4 ∣ + 6 = - 5

2 - 4 ∣ 7 + 5 x ∣ = - 26

∣ 4 y - 10 ∣ = 20

∣ 2 x - 7 ∣ + 8 = 3 x

∣ 2 x - 2 ∣ + 3 = 5
