|2-b|=2

Lösung

∣ 2 - b ∣ = 2

b = 0 or b = 4

Schritte zur Lösung

∣ 2 - b ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

b = 0 or b = 4

∣ 3 x + 6 ∣ = - 4

∣ - y + 8 ∣ = 15

∣ 5 y + 9 ∣ - 16 = 0

0 = - 5 ∣ w ∣

- 14 = 7 - 3 ∣ - 4 n - 2 ∣
