Lösung

∣ 2 t - 4 ∣ = 8

t = - 2 or t = 6

Schritte zur Lösung

∣ 2 t - 4 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 t - 4 = - 8 or 2 t - 4 = 8

2 t - 4 = - 8 or 2 t - 4 = 8

t = - 2 or t = 6

∣ 2 x + 5 ∣ + 12 = 7

∣ x - 1 ∣ 1 + 7 = 23

∣ 3 x - 3 ∣ = 6

2 + ∣ 4 x - 6 ∣ = 99

∣ 5 x - 6 ∣ - 13 = - 8
