|-2x-12|=10

Lösung

∣ - 2 x - 12 ∣ = 10

x = - 11 or x = - 1

Schritte zur Lösung

∣ - 2 x - 12 ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 2 x - 12 = - 10 or - 2 x - 12 = 10

- 2 x - 12 = - 10 or - 2 x - 12 = 10

x = - 11 or x = - 1

2 = ∣ m + 23 ∣

- 7 ∣ - 8 x - 6 ∣ = - 70

f (- 2) = ∣ x + 3 ∣, x \leq - 1

- 2 ∣ 3 y + 5 ∣ = 0

- 2 ∣ - 8 x ∣ = - 16
