Schritte zur Lösung

∣ 9 - 4 z ∣ = 53

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

9 - 4 z = - 53 or 9 - 4 z = 53

9 - 4 z = - 53 or 9 - 4 z = 53

z = - 11 or z = \frac{31}{2}

∣ 2.5 x - 25 ∣ = 0.5

- 2 ∣ 3 x + 1 ∣ = 20

2 ∣ g - 5 ∣ + 7 = 13

x^{2} - ∣ x ∣ = 0

5 ∣ 2 x - 1 ∣ = 5
