x = - 2.03333 \dots or x = 1.96666 \dots

Schritte zur Lösung

∣ 3 x + 0.1 ∣ = 6

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x + 0.1 = - 6 or 3 x + 0.1 = 6

3 x + 0.1 = - 6 or 3 x + 0.1 = 6

x = - 2.03333 \dots or x = 1.96666 \dots

∣ 2 b + 3 ∣ - 7 = 8

∣ x + 19 ∣ = 25

2 ∣ 7 y - 8 ∣ = - 28

9 ∣ 10 x + 9 ∣ - 2 = - 11

∣ 2 x - 11 ∣ = 7
