Lösung

\frac{1}{2} x - 4 = 3

x = 2 or x = 14

Schritte zur Lösung

\frac{1}{2} x - 4 = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{1}{2} x - 4 = - 3 or \frac{1}{2} x - 4 = 3

\frac{1}{2} x - 4 = - 3 or \frac{1}{2} x - 4 = 3

x = 2 or x = 14

\frac{1}{2} x - 4 = 5

- x^{2} + ∣ 9 x ∣ + 10 = 0

2 = ∣ s + 2 ∣

11 - ∣ x - 7 ∣ = 0

∣ 3 - 4 x ∣ = 8
