x = - 13 or x = 3

Schritte zur Lösung

∣ 5 + x ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 + x = - 8 or 5 + x = 8

5 + x = - 8 or 5 + x = 8

x = - 13 or x = 3

2 ∣ x - 8 ∣ - 10 = - 4

∣ X + 4 ∣ = 2 X + 2

∣ w - 4 ∣ = 11

5 ∣ p - 4 ∣ + 8 = 53

- 4 ∣ b - 2 ∣ - 9 = - 37
