|x-3|=28

Lösung

∣ x - 3 ∣ = 28

x = - 25 or x = 31

Schritte zur Lösung

∣ x - 3 ∣ = 28

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 3 = - 28 or x - 3 = 28

x - 3 = - 28 or x - 3 = 28

x = - 25 or x = 31

∣ 2 x - 10 ∣ = ∣ 7 x + 19 ∣

∣ 2 n + 5 ∣ = 11

x = - 3^{2} + 5

3.2 - ∣ 2 + x ∣ = 2.9

- 2 ∣ 4 m - 1 ∣ = - 6
