Lösung

∣ 5 x - 15 ∣ = 20

x = - 1 or x = 7

Schritte zur Lösung

∣ 5 x - 15 ∣ = 20

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 x - 15 = - 20 or 5 x - 15 = 20

5 x - 15 = - 20 or 5 x - 15 = 20

x = - 1 or x = 7

∣ 2 x - 2 ∣ = \frac{1}{3}

- 4 ∣ x + 5 ∣ + 10 = 10

3 ∣ x - 1 ∣ - 3 = 9

∣ m + 4 ∣ = - 6

- 2 ∣ x + 4 ∣ = - 8
