Schritte zur Lösung

∣ 3 x - 1 ∣ = \frac{1}{3}

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

x = \frac{2}{9} or x = \frac{4}{9}

∣ 2 x - 1 ∣ = x + 3

∣ 3 u - 9 ∣ = 3

∣ 6 x - 1 ∣ + 7 = 18

5 ∣ 6 y - 4 ∣ - 5 = 20

∣ w - 1 ∣ = 2
