Schritte zur Lösung

∣ 4 m + 7 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 m + 7 = - 18 or 4 m + 7 = 18

4 m + 7 = - 18 or 4 m + 7 = 18

m = - \frac{25}{4} or m = \frac{11}{4}

2 ∣ x - 1 ∣ = 4

2 ∣ 5 x + 3 ∣ = 16

4 ∣ 3 x - 9 ∣ = 36

- 4 ∣ x + 7 ∣ = - 16

∣ 9 + 8 x ∣ = 31
