|2x-2|=4

Lösung

∣ 2 x - 2 ∣ = 4

x = - 1 or x = 3

Schritte zur Lösung

∣ 2 x - 2 ∣ = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 2 = - 4 or 2 x - 2 = 4

2 x - 2 = - 4 or 2 x - 2 = 4

x = - 1 or x = 3

∣ 3 p + 2 ∣ = 7

- 1 = 2 ∣ x - 4 ∣ - 3

0 = ∣ x ∣ - 3

15 = 2 - ∣ p - 3 ∣

\frac{x}{3} - 1 + 2 = 0
