|3-3x|=5

Lösung

∣ 3 - 3 x ∣ = 5

x = - \frac{2}{3} or x = \frac{8}{3}

Dezimale

x = - 0.66666 \dots, x = 2.66666 \dots

Schritte zur Lösung

∣ 3 - 3 x ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 - 3 x = - 5 or 3 - 3 x = 5

3 - 3 x = - 5 or 3 - 3 x = 5

x = - \frac{2}{3} or x = \frac{8}{3}

so l v e f or y, ∣ x + y ∣ = 1

∣ 2 x ∣ = 84

x - ∣ 2 x - 1 ∣ = 4 x + 2

- 3 ∣ m ∣ = - 9

2 ∣ x + 4 ∣ = 8 x - 2
