Schritte zur Lösung

\frac{9}{4} x + 1 = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{9}{4} x + 1 = - 3 or \frac{9}{4} x + 1 = 3

\frac{9}{4} x + 1 = - 3 or \frac{9}{4} x + 1 = 3

x = - \frac{16}{9} or x = \frac{8}{9}

- 8 + 6 ∣ 8 x - 9 ∣ = 16

∣ 4 x + 4 ∣ = 15

∣ c + 380 ∣ = 15

∣ - 5 x + 12 ∣ = - 2 x + 1

∣ b + 8 ∣ + 4 = 5
