Schritte zur Lösung

∣ 3 x + 11 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x + 11 = - 18 or 3 x + 11 = 18

3 x + 11 = - 18 or 3 x + 11 = 18

x = - \frac{29}{3} or x = \frac{7}{3}

5 + ∣ 2 x - 6 ∣ = 9

15 = ∣ - 4 b + 12 ∣

8 - 8 ∣ - 5 b + 4 ∣ = - 120

∣ 10 + 2 n ∣ = 28

x^{2} - 2 = x + 4
