|2b-2|=2

Lösung

∣ 2 b - 2 ∣ = 2

b = 0 or b = 2

Schritte zur Lösung

∣ 2 b - 2 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 b - 2 = - 2 or 2 b - 2 = 2

2 b - 2 = - 2 or 2 b - 2 = 2

b = 0 or b = 2

4 - 6 ∣ 5 x - 2 ∣ = - 26

∣ 8 x - 2 ∣ = 66

\frac{x}{3} - 2 = 4

10 - 3 ∣ 3 + 6 x ∣ = 1

∣ 5 y - 7 ∣ + 2 = 4
