|r-6|=3

Lösung

∣ r - 6 ∣ = 3

r = 3 or r = 9

Schritte zur Lösung

∣ r - 6 ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

r - 6 = - 3 or r - 6 = 3

r - 6 = - 3 or r - 6 = 3

r = 3 or r = 9

28 = ∣ c - 2 ∣

∣ 3 x - 7 ∣ - 7 = x

36 = ∣ 6 - 5 y ∣

21 = ∣ 5 - 4 b ∣

5 = ∣ 5 y ∣
