Lösung

∣ b + 17 ∣ = 49

b = - 66 or b = 32

Schritte zur Lösung

∣ b + 17 ∣ = 49

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

b + 17 = - 49 or b + 17 = 49

b + 17 = - 49 or b + 17 = 49

b = - 66 or b = 32

33 = ∣ y + 19 ∣

3 ∣ 4 x - 1 ∣ - 5 = 10

∣ 2 x + 8 ∣ = 3 x + 7

4 ∣ 2 x + 4 ∣ - 7 = 17

13 = ∣ b - 26 ∣
