Lösung

∣ 8 c - 4 ∣ = 20

c = - 2 or c = 3

Schritte zur Lösung

∣ 8 c - 4 ∣ = 20

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

8 c - 4 = - 20 or 8 c - 4 = 20

8 c - 4 = - 20 or 8 c - 4 = 20

c = - 2 or c = 3

\frac{4}{3} ∣ 3 w - 6 ∣ = 16

2 ∣ x - 4 ∣ - 3 = \frac{2}{3} x - 3

∣ 5 x - 1 ∣ = x + 3

∣ 8 - 2 x ∣ = 2 ∣ x - 4 ∣

∣ x - 5 ∣ = 18
