Lösung

∣ 3 x + 8 ∣ = 2

x = - \frac{10}{3} or x = - 2

Dezimale

x = - 3.33333 \dots, x = - 2

Schritte zur Lösung

∣ 3 x + 8 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x + 8 = - 2 or 3 x + 8 = 2

3 x + 8 = - 2 or 3 x + 8 = 2

x = - \frac{10}{3} or x = - 2

5 = ∣ x ∣ + 3

4 ∣ x + 5 ∣ + 2 = 0

∣ 3 x - 2 ∣ = - 2

\frac{1}{4} x + 5 = 3

∣ x ∣ + 11 = 11
