∣ 3 x - 1 ∣ = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x - 1 = - 4 or 3 x - 1 = 4

3 x - 1 = - 4 or 3 x - 1 = 4

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

∣ x ∣ + x = 0

∣ x - 1 ∣ = 4 - x

∣ x - 1 ∣ = ∣ x + 4 ∣

x^{2} + x + 2 - x^{2} - x + 1 = ∣ 2 x + 1 ∣

\frac{x}{2 + 3} \cdot (5 - 6 x) + (12 x - 2) \frac{x}{4 + 3} = 0
