∣ 2 x + 3 ∣ = 2

x = - \frac{5}{2} or x = - \frac{1}{2}

Dezimale

x = - 2.5, x = - 0.5

Schritte zur Lösung

∣ 2 x + 3 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x + 3 = - 2 or 2 x + 3 = 2

2 x + 3 = - 2 or 2 x + 3 = 2

x = - \frac{5}{2} or x = - \frac{1}{2}

∣ 8 x + 3 ∣ = 7

- 2 ∣ x - 6 ∣ - 17 = 3

7 ∣ x - 6 ∣ = 4

2 = ln y - x^{2}

2 x + 1 = 5 ∣ 4 - 2 x ∣ - 10
