t = - 100 or t = 80

Schritte zur Lösung

∣ t + 10 ∣ = 90

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

t + 10 = - 90 or t + 10 = 90

t + 10 = - 90 or t + 10 = 90

t = - 100 or t = 80

∣ x + 2 ∣ = - 2 x + 5

∣ 6 m ∣ + 2 = 74

- 4 ∣ n + 7 ∣ = - 56

∣ - 3 - 2 x ∣ = 2 - 4 x

3 ∣ 7 - 2 x ∣ + 10 = 1
