\frac{3}{5} z - 3 = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{3}{5} z - 3 = - 12 or \frac{3}{5} z - 3 = 12

\frac{3}{5} z - 3 = - 12 or \frac{3}{5} z - 3 = 12

z = - 15 or z = 25

∣ x - 2.5 ∣ = 6

∣ x - 1 ∣ = ∣ 2 x + 1 ∣ - 1

∣ 3 - 7 x ∣ = 19

2 ∣ 5 x ∣ = 50

∣ x + 3 ∣ = 3 + 2 x
