| 1/2 x+5|=3

Lösung

\frac{1}{2} x + 5 = 3

x = - 16 or x = - 4

Schritte zur Lösung

\frac{1}{2} x + 5 = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{1}{2} x + 5 = - 3 or \frac{1}{2} x + 5 = 3

\frac{1}{2} x + 5 = - 3 or \frac{1}{2} x + 5 = 3

x = - 16 or x = - 4

\frac{x}{5} = 1

3 ∣ 2 x + 2 ∣ - 2 x = x + 3

5 ∣ x - 4 ∣ - 5 = 2

∣ 3 x - 4 ∣ = 11

∣ x + 1 ∣ = x - 3
