Schritte zur Lösung

∣ 13 x + 1 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

13 x + 1 = - 12 or 13 x + 1 = 12

13 x + 1 = - 12 or 13 x + 1 = 12

x = - 1 or x = \frac{11}{13}

x^{2} + 5 ∣ x ∣ + 4 = 0

∣ 3 y - 9 ∣ = 6

a^{2} = ∣ a ∣

∣ 2 x - 36 ∣ = 14

3 ∣ x - 4 ∣ = 7
