Schritte zur Lösung

∣ 20 - 9 m ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

20 - 9 m = - 7 or 20 - 9 m = 7

20 - 9 m = - 7 or 20 - 9 m = 7

m = \frac{13}{9} or m = 3

- 12 = ∣ d + 6 ∣

2 ∣ q ∣ = 6

9 + 9 ∣ 8 x + 1 ∣ = 18

∣ 2 \cdot x + 5 ∣ - 5 = 9

n (x) = 7 ∣ x ∣ + 3 x - 1
