x = - 60 or x = 50

Schritte zur Lösung

∣ x + 5 ∣ = 55

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 5 = - 55 or x + 5 = 55

x + 5 = - 55 or x + 5 = 55

x = - 60 or x = 50

∣ 5 x - 4 ∣ + 2 = 9

∣ 3 x + 7 ∣ = 13

∣ 9 + 4 d ∣ = 15

5 - \frac{3}{4} k = 7

0 = ∣ 3 x + 1 ∣ - 5
