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

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

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

∣ 2 x + 3 ∣ - x = 3

x^{2} - 5 x - 1 = 7

5 ∣ b + 7 ∣ = 80

\frac{6 ∣ x - 2 ∣}{4} = 3 x

3 ∣ 2 x - 5 ∣ = - 9 x
