x = - 5 or x = 1

Schritte zur Lösung

∣ 6 x + 12 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

6 x + 12 = - 18 or 6 x + 12 = 18

6 x + 12 = - 18 or 6 x + 12 = 18

x = - 5 or x = 1

∣ - 2 k + 2 ∣ - 5 = - 5

- \frac{2}{3} ∣ 2 + x ∣ = 4

∣ 6 x + 12 ∣ = 24

\frac{9}{4} x + 1 = 3

- 8 + 6 ∣ 8 x - 9 ∣ = 16
