Schritte zur Lösung

∣ - 5 c + 1 ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 5 c + 1 = - 7 or - 5 c + 1 = 7

- 5 c + 1 = - 7 or - 5 c + 1 = 7

c = - \frac{6}{5} or c = \frac{8}{5}

8 + ∣ 4 x + 7 ∣ = 17

∣ 2 x - 3 ∣ = 4 x - 1

∣ y - 1 ∣ + 17 = 23

4 ∣ 7 y + 2 ∣ - 8 = - 7

43 = ∣ y - 8 ∣
