x = - 2.5, x = - 0.5

Schritte zur Lösung

∣ 12 x + 18 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

12 x + 18 = - 12 or 12 x + 18 = 12

12 x + 18 = - 12 or 12 x + 18 = 12

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

72 = 3 ∣ z ∣

- 3 ∣ x ∣ - 5 = - 17

∣ x ∣ \cdot (x + 3) = - 2

0 = ∣ s + 1 ∣

- 3 ∣ x ∣ - 5 = - 29
