∣ 4 x - 3 ∣ = 6

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x - 3 = - 6 or 4 x - 3 = 6

4 x - 3 = - 6 or 4 x - 3 = 6

x = - \frac{3}{4} or x = \frac{9}{4}

∣ 7 - 3 x ∣ + 10 = 8

so l v e f or y, x = ∣ 5 y ∣

∣ x + 1 ∣ - ∣ x ∣ = 0

∣ - 4 x - 8 ∣ = 12

- x^{2} + 6 = ∣ x ∣
