Schritte zur Lösung

∣ 3 v + 5 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 v + 5 = - 8 or 3 v + 5 = 8

3 v + 5 = - 8 or 3 v + 5 = 8

v = - \frac{13}{3} or v = 1

∣ 2 x + 5 ∣ + 9 = 6

∣ 2 x - 1 ∣ - 4 = 3 x + 7

∣ x + 4 ∣ = 3 x - 8

∣ 9 - 2 x ∣ = 3 x + 10

\frac{p}{2} + 7 = 11
