Schritte zur Lösung

∣ 3 x - 9 ∣ = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x - 9 = - 4 or 3 x - 9 = 4

3 x - 9 = - 4 or 3 x - 9 = 4

x = \frac{5}{3} or x = \frac{13}{3}

0 = ∣ 3 x - 2 ∣

∣ m + 2 ∣ + 7 = 13

∣ 5 x - 15 ∣ = 5

∣ 0.5 x - 0.75 ∣ + 4.6 = 0.25

∣ x ∣ = 53.1
