Schritte zur Lösung

∣ 3 x - 2 ∣ = 19

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x - 2 = - 19 or 3 x - 2 = 19

3 x - 2 = - 19 or 3 x - 2 = 19

x = - \frac{17}{3} or x = 7

∣ 2 x + 5 ∣ + 4 = 17

∣ x + 3 ∣ = 2 x + 4

∣ x + 1 ∣ + ∣ 2 x - 3 ∣ = 8

∣ x + 3 ∣ = x^{2} - 4 x - 3

\frac{∣ 3 - 6 w ∣}{5} - 16 = - 7
