|v+8|=7

Lösung

∣ v + 8 ∣ = 7

v = - 15 or v = - 1

Schritte zur Lösung

∣ v + 8 ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

v + 8 = - 7 or v + 8 = 7

v + 8 = - 7 or v + 8 = 7

v = - 15 or v = - 1

2 ∣ x - 1 ∣ = 8

∣ 3 x - 4 ∣ = x^{2}

0 = ∣ x - 1 ∣ - 2

\frac{x}{3} + 4 = 5

∣ v ∣ = 2
