Schritte zur Lösung

∣ 3 x + 8 ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x + 8 = - 3 or 3 x + 8 = 3

3 x + 8 = - 3 or 3 x + 8 = 3

x = - \frac{11}{3} or x = - \frac{5}{3}

∣ 3 x - 2 ∣ = - 8

∣ 3 x - 2 ∣ = \frac{3}{2}

∣ w ∣ - 20 = - 14

\frac{4}{5} - 2 x = 4

8 ∣ - 5 p ∣ - 7 = - 15
