Schritte zur Lösung

∣ 3 x + 3 ∣ = 13

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x + 3 = - 13 or 3 x + 3 = 13

3 x + 3 = - 13 or 3 x + 3 = 13

x = - \frac{16}{3} or x = \frac{10}{3}

∣ 3 x + 3 ∣ = 27

12 = 71 - ∣ 5 x + 9 ∣

- 8 ∣ 6 n - 7 ∣ - 6 = - 14

∣ 2 x - 1 ∣ = - 7

∣ - 7 n ∣ = 7
