Schritte zur Lösung

∣ 8 y - 4 ∣ = 13

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

8 y - 4 = - 13 or 8 y - 4 = 13

8 y - 4 = - 13 or 8 y - 4 = 13

y = - \frac{9}{8} or y = \frac{17}{8}

∣ 4 v + 10 ∣ = 2

∣ 4 x + 8 ∣ = - x + 45

2 x + ∣ x - 1 ∣ = 5

10 = ∣ n ∣ + 5

∣ 15 + m ∣ = - 2 m + 3
