|r+15|=45

Lösung

∣ r + 15 ∣ = 45

r = - 60 or r = 30

Schritte zur Lösung

∣ r + 15 ∣ = 45

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

r + 15 = - 45 or r + 15 = 45

r + 15 = - 45 or r + 15 = 45

r = - 60 or r = 30

6 = 4 ∣ m + 8 ∣ + 6

6 ∣ x ∣ + 1 = 7

- ∣ - 3 c ∣ = - 66

∣ - 4 + x ∣ = 3

∣ - 4 + x ∣ = 1
