|8v-12|=68

Lösung

∣ 8 v - 12 ∣ = 68

v = - 7 or v = 10

Schritte zur Lösung

∣ 8 v - 12 ∣ = 68

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

8 v - 12 = - 68 or 8 v - 12 = 68

8 v - 12 = - 68 or 8 v - 12 = 68

v = - 7 or v = 10

∣ 6 x - 1 ∣ + 7 = 7

∣ 3 x ∣ + 8 = 17

x^{2} + 6 x - 8 = 8

x^{2} - 13 = 3

- 2 ∣ x + 8 ∣ = 20
