∣ x - 4 ∣ = \frac{6}{7}

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 4 = - \frac{6}{7} or x - 4 = \frac{6}{7}

x - 4 = - \frac{6}{7} or x - 4 = \frac{6}{7}

x = \frac{22}{7} or x = \frac{34}{7}

∣ 4 x - 7 ∣ = 13

∣ x + 8 ∣ = 9

6 - ∣ 3 x + 6 ∣ = 3

4 ∣ m ∣ = - 20

so l v e f or x, ∣ x + 2 y ∣ = 2
