Schritte zur Lösung

∣ x + 2 ∣ = \frac{1}{3}

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 2 = - \frac{1}{3} or x + 2 = \frac{1}{3}

x + 2 = - \frac{1}{3} or x + 2 = \frac{1}{3}

x = - \frac{7}{3} or x = - \frac{5}{3}

\frac{∣ x ∣}{8} = 3

∣ 2 x + 3 ∣ - 7 = 0

∣ 3 x + 2 ∣ - 2 = 6

∣ z ∣ + 4 = 5

8 ∣ 8 n + 1 ∣ = - 56
