Schritte zur Lösung

∣ 20 x + 18 ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

20 x + 18 = - 10 or 20 x + 18 = 10

20 x + 18 = - 10 or 20 x + 18 = 10

x = - \frac{7}{5} or x = - \frac{2}{5}

∣ - 2 x - 19 ∣ = 4 x + 1

1 - \frac{3}{4} k = 11

0 = ∣ p - 3 ∣

∣ r - 45 ∣ = 15

7 = ∣ 4 g - 1 ∣ - 1
