Schritte zur Lösung

∣ 8 x + 3 ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

8 x + 3 = - 7 or 8 x + 3 = 7

8 x + 3 = - 7 or 8 x + 3 = 7

x = - \frac{5}{4} or x = \frac{1}{2}

- 2 ∣ x - 6 ∣ - 17 = 3

7 ∣ x - 6 ∣ = 4

2 = ln y - x^{2}

2 x + 1 = 5 ∣ 4 - 2 x ∣ - 10

- 3 ∣ x + 4 ∣ = - 21
