|6c-18|=30

Lösung

∣ 6 c - 18 ∣ = 30

c = - 2 or c = 8

Schritte zur Lösung

∣ 6 c - 18 ∣ = 30

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

6 c - 18 = - 30 or 6 c - 18 = 30

6 c - 18 = - 30 or 6 c - 18 = 30

c = - 2 or c = 8

2 ∣ 8 x + 5 ∣ + 10 = 32

∣ x ∣ - 5 = 0

20 - 4 ∣ a ∣ = 12

∣ 8 - a ∣ = - 2

∣ 7 m ∣ + 2 = 37
