∣ - 11 x + 3 ∣ = \frac{25}{2}

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 11 x + 3 = - \frac{25}{2} or - 11 x + 3 = \frac{25}{2}

- 11 x + 3 = - \frac{25}{2} or - 11 x + 3 = \frac{25}{2}

x = - \frac{19}{22} or x = \frac{31}{22}

∣ - 6 z ∣ = 48

x^{2} + x - 3 = ∣ 2 x - 1 ∣

- 16 = - 2 ∣ b ∣

∣ 2 x - 3 ∣ - 7 = 14

∣ 5 - 2 y ∣ + 3 = 8
