Lösung

∣ a - 15 ∣ = 2828

a = - 2813 or a = 2843

Schritte zur Lösung

∣ a - 15 ∣ = 2828

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

a - 15 = - 2828 or a - 15 = 2828

a - 15 = - 2828 or a - 15 = 2828

a = - 2813 or a = 2843

x^{2} - 2 ∣ x - 1 ∣ = 2

∣ 10 + 9 k ∣ = 35

9 ∣ 7 z + 5 ∣ = 27

∣ 18 x - 5 ∣ = 0

92 = ∣ r - 900 ∣ - 8
