∣ t + 8 ∣ = 11

t = - 19 or t = 3

Schritte zur Lösung

∣ t + 8 ∣ = 11

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

t + 8 = - 11 or t + 8 = 11

t + 8 = - 11 or t + 8 = 11

t = - 19 or t = 3

∣ 2 x - 9 ∣ = 7

∣ 3 x + 8 ∣ = 6

∣ 3 x - 2 ∣ = 10

6 ∣ 2 x - 3 ∣ - 9 = 33

∣ x - 2 ∣ = 6 x + 18
