a, ∣ a - 1 ∣ = 12

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 c - 2 ∣ = ∣ 2 c + 4 ∣

∣ x - 2 ∣ \cdot ∣ x + 1 ∣ = 10

∣ 2 x - 4 ∣ + 3 = 15

∣ 3 x + 5 ∣ = 5 x + 11

22 = ∣ 4 x + 10 ∣
