|t+2|=5

Lösung

∣ t + 2 ∣ = 5

t = - 7 or t = 3

Schritte zur Lösung

∣ t + 2 ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

t + 2 = - 5 or t + 2 = 5

t + 2 = - 5 or t + 2 = 5

t = - 7 or t = 3

5 ∣ x - 6 ∣ = 18

5 ∣ x - 6 ∣ = 22

5 ∣ x - 6 ∣ = 28

5 ∣ x - 6 ∣ = 26

∣ - 6 + n ∣ = 3
