Schritte zur Lösung

∣ 12 - 9 m ∣ = 30

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

12 - 9 m = - 30 or 12 - 9 m = 30

12 - 9 m = - 30 or 12 - 9 m = 30

m = - 2 or m = \frac{14}{3}

∣ 2 - 4 x ∣ = 1

9 ∣ 2 - 2 x ∣ = 3 x + 3

∣ 4 y + 9 ∣ = 13

50 = ∣ t - 410 ∣

- 2 ∣ x - 5 ∣ = - 4
