∣ - 3 r ∣ = 12

r = - 4 or r = 4

Schritte zur Lösung

∣ - 3 r ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 3 r = - 12 or - 3 r = 12

- 3 r = - 12 or - 3 r = 12

r = - 4 or r = 4

∣ x - 4 ∣ - 3 = - 12

3 ∣ x ∣ = 4 - x^{2}

∣ h - 5 ∣ - 3 = 7

∣ 2 a + 5 ∣ = 17

∣ - 8 w - 40 ∣ - 9 = 71
