Schritte zur Lösung

∣ - 4 c + 13 ∣ = 15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 4 c + 13 = - 15 or - 4 c + 13 = 15

- 4 c + 13 = - 15 or - 4 c + 13 = 15

c = - \frac{1}{2} or c = 7

4 ∣ 2 y - 7 ∣ + 13 = 9

∣ 2 x - 3 ∣ + 5 = 10

∣ 5 x ∣ = 5

∣ 3 x - 3 ∣ + 9 = x

2 ∣ x + 8 ∣ = 20
