|5x-1|=21

Lösung

∣ 5 x - 1 ∣ = 21

x = - 4 or x = \frac{22}{5}

Dezimale

x = - 4, x = 4.4

Schritte zur Lösung

∣ 5 x - 1 ∣ = 21

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 x - 1 = - 21 or 5 x - 1 = 21

5 x - 1 = - 21 or 5 x - 1 = 21

x = - 4 or x = \frac{22}{5}

3 x = x^{2} - 10

x + 5 = ∣ 2 x ∣

0 = ∣ t - 3 ∣

x^{2} = 1

∣ x + 1 ∣ = - 7
