|c-7|=2

Lösung

∣ c - 7 ∣ = 2

c = 5 or c = 9

Schritte zur Lösung

∣ c - 7 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

c - 7 = - 2 or c - 7 = 2

c - 7 = - 2 or c - 7 = 2

c = 5 or c = 9

∣ x - 1 ∣ = - 2 x

x^{2} - 5 x = - 5 x + 9

∣ 6 x + 6 ∣ = 6

4 + 5 ∣ v ∣ = 29

10 - x^{2} = 26
