Schritte zur Lösung

∣ 2 x + 2 ∣ = 13

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x + 2 = - 13 or 2 x + 2 = 13

2 x + 2 = - 13 or 2 x + 2 = 13

x = - \frac{15}{2} or x = \frac{11}{2}

∣ a ∣ - 3 = 8

∣ 2 x - 3 ∣ - 3 = 4 x^{4} x

∣ 8 - 5 v ∣ = 43

3 + 9 ∣ - 4 x - 9 ∣ = 75

- 2 ∣ y ∣ = 10
