|2x-7|=13

Lösung

∣ 2 x - 7 ∣ = 13

x = - 3 or x = 10

Schritte zur Lösung

∣ 2 x - 7 ∣ = 13

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 7 = - 13 or 2 x - 7 = 13

2 x - 7 = - 13 or 2 x - 7 = 13

x = - 3 or x = 10

∣ 2 y - 7 ∣ = ∣ 5 - 2 y ∣

x^{2} + 4 - 4 ∣ x - 7 ∣ = 14 x - 49

x \cdot ∣ x - 4 ∣ = 3

0.2 x + 6 = - 7.3 ∣ x - 9 ∣ + 22, y = 0

∣ 3 x - 2 ∣ + 6 = 10
