x = 4 or x = 12

Schritte zur Lösung

- 4 + \frac{1}{2} x = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 4 + \frac{1}{2} x = - 2 or - 4 + \frac{1}{2} x = 2

- 4 + \frac{1}{2} x = - 2 or - 4 + \frac{1}{2} x = 2

x = 4 or x = 12

∣ 7 x - 5 ∣ = 44

∣ 5 w + 15 ∣ = 5

∣ x - 6 ∣ + 8 = 17

∣ x - 6 ∣ + 8 = 15

∣ x + 7 ∣ = 13
