Schritte zur Lösung

∣ 5 - 2 x ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 - 2 x = - 18 or 5 - 2 x = 18

5 - 2 x = - 18 or 5 - 2 x = 18

x = - \frac{13}{2} or x = \frac{23}{2}

- 2 ∣ 7 - 9 c ∣ + 7 = - 15

20 = ∣ 9 - 4 y ∣

∣ 5 x - 2 ∣ = 13

∣ 5 x - 7 ∣ + 1 = 3 x

∣ 2 x + 5 ∣ - 10 = 3 x
