| b/4 |=8

Lösung

\frac{b}{4} = 8

b = - 32 or b = 32

Schritte zur Lösung

\frac{b}{4} = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{b}{4} = - 8 or \frac{b}{4} = 8

\frac{b}{4} = - 8 or \frac{b}{4} = 8

b = - 32 or b = 32

∣ 0.127 x + 9 ∣ = x^{2}

11 = ∣ 3 x + 5 ∣

4 ∣ 3 (x + 3) (x - 3) ∣ - 4 = 4

3 ∣ y + 5 ∣ + 7 = 10

3 + 9 ∣ - 5 n ∣ = 48
