Schritte zur Lösung

∣ 3 x + 8 ∣ = 29

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x + 8 = - 29 or 3 x + 8 = 29

3 x + 8 = - 29 or 3 x + 8 = 29

x = - \frac{37}{3} or x = 7

∣ x + 3 ∣ = 5 - x

3 ∣ v - 3 ∣ = 9

∣ x + 142 ∣ = 4

\frac{∣ 3 v - 2 ∣}{5} = 4

∣ x + 5 ∣ + 7 = 3
