|f+10|=1

Lösung

∣ f + 10 ∣ = 1

f = - 11 or f = - 9

Schritte zur Lösung

∣ f + 10 ∣ = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

f + 10 = - 1 or f + 10 = 1

f + 10 = - 1 or f + 10 = 1

f = - 11 or f = - 9

6 - ∣ 8 + 5 x ∣ = 5

5 ∣ 2 x - 4 ∣ + 1 = 11

∣ 5 - b ∣ = 12

∣ 5 - 2 x ∣ = 18

- 2 ∣ 7 - 9 c ∣ + 7 = - 15
