|2x-12|=10

Lösung

∣ 2 x - 12 ∣ = 10

x = 1 or x = 11

Schritte zur Lösung

∣ 2 x - 12 ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 12 = - 10 or 2 x - 12 = 10

2 x - 12 = - 10 or 2 x - 12 = 10

x = 1 or x = 11

∣ - 7 x ∣ = 21

8 = ∣ s ∣ - 2

0 = - ∣ g + 5 ∣

∣ r ∣ = 9

- 5 + 9 ∣ - 5 x - 8 ∣ = - 77
