|(-9+v)/8 |=3

Lösung

\frac{- 9 + v}{8} = 3

v = - 15 or v = 33

Schritte zur Lösung

\frac{- 9 + v}{8} = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{- 9 + v}{8} = - 3 or \frac{- 9 + v}{8} = 3

\frac{- 9 + v}{8} = - 3 or \frac{- 9 + v}{8} = 3

v = - 15 or v = 33

2 \frac{n}{6} = 1

∣ 3 x + 4 ∣ + 7 = 5

6 ∣ 9 - 4 x ∣ + 7 = 49

21 = ∣ b + 30 ∣ - 9

∣ 3 x + 7 ∣ = 2 x + 3
