Lösung

∣ t - 50 ∣ = 30

t = 20 or t = 80

Schritte zur Lösung

∣ t - 50 ∣ = 30

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

t - 50 = - 30 or t - 50 = 30

t - 50 = - 30 or t - 50 = 30

t = 20 or t = 80

∣ p + 5 ∣ = 2

3 - \frac{1}{2} ∣ r + 9 ∣ = - 11

∣ x - 1 ∣ = ∣ 2 x ∣

\frac{3}{5} ∣ 10 - 5 x ∣ + 8 = 29

∣ x - 5 ∣ = x^{2} - 7 x + 10
