|2x-5|=25

Lösung

∣ 2 x - 5 ∣ = 25

x = - 10 or x = 15

Schritte zur Lösung

∣ 2 x - 5 ∣ = 25

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 5 = - 25 or 2 x - 5 = 25

2 x - 5 = - 25 or 2 x - 5 = 25

x = - 10 or x = 15

3 ∣ 2 d + 9 ∣ + 13 = 10

∣ x - 4 ∣ = ∣ 4 - x ∣

\frac{1}{4} x + 12 = 16

∣ x + 2 ∣ = 2 ∣ x - 1 ∣

- 3 ∣ 2 x + 1 ∣ + 10 = - 2
