|t+5|=8

Lösung

∣ t + 5 ∣ = 8

t = - 13 or t = 3

Schritte zur Lösung

∣ t + 5 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

t + 5 = - 8 or t + 5 = 8

t + 5 = - 8 or t + 5 = 8

t = - 13 or t = 3

∣ 4 - 2 x ∣ + 5 = 9

3 - 8 ∣ a + 6 ∣ = - 13

∣ t ∣ - 2 = - 1

∣ 5 x - 5 ∣ = 15

∣ 5 x - 2 ∣ = 4 x - 5
