Schritte zur Lösung

∣ q + 3.5 q ∣ = 90

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

q + 3.5 q = - 90 or q + 3.5 q = 90

q + 3.5 q = - 90 or q + 3.5 q = 90

q = - 20 or q = 20

∣ 3 - 4 t ∣ + 6 = 25

∣ - 9 b ∣ + 23 = 104

A (x) = ∣ 9 - 2 x ∣

∣ 3 x + 1 ∣ = 2 x + 3

∣ x + 8 ∣ + 9 = 2
