Schritte zur Lösung

∣ 2 - 3 y ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 - 3 y = - 3 or 2 - 3 y = 3

2 - 3 y = - 3 or 2 - 3 y = 3

y = - \frac{1}{3} or y = \frac{5}{3}

∣ 2 x + 7 ∣ = 5

∣ 4 x - 5 ∣ + 5 x + 2 = 0

9 + 2 ∣ 4 x - 5 ∣ = 13

13 = ∣ - 2 x + 5 ∣

9 - 2 ∣ 2 x + 1 ∣ = 5
