Schritte zur Lösung

∣ - 3 z - 4 ∣ = 17

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 3 z - 4 = - 17 or - 3 z - 4 = 17

- 3 z - 4 = - 17 or - 3 z - 4 = 17

z = - 7 or z = \frac{13}{3}

∣ g - 4 ∣ = - 14

∣ x - 20 ∣ = 4646

∣ 2 - x ∣ = 2

x^{2} - 7 x + 8 = 2

∣ y + 405 ∣ + 3 = 48
