Schritte zur Lösung

∣ 5 a + 8 ∣ = 23

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 a + 8 = - 23 or 5 a + 8 = 23

5 a + 8 = - 23 or 5 a + 8 = 23

a = - \frac{31}{5} or a = 3

- 4 ∣ x ∣ + 3 = - 5

∣ x ∣ = x^{2} + x - 4

∣ x ∣ = x^{2} + x - 2

8 - ∣ - 7 p + 8 ∣ = 2

2 = ∣ m - 4 ∣
