|3(x+1)|=15

Lösung

∣ 3 (x + 1) ∣ = 15

x = - 6 or x = 4

Schritte zur Lösung

∣ 3 (x + 1) ∣ = 15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 (x + 1) = - 15 or 3 (x + 1) = 15

3 (x + 1) = - 15 or 3 (x + 1) = 15

x = - 6 or x = 4

2 ∣ 4 x - 10 ∣ + 8 = 12

- 2 ∣ p + 6 ∣ - 3 = - 17

∣ x ∣ - 17 = - 13

∣ 3 x ∣ = - x + 12

2 - 3 ∣ 7 x + 5 ∣ = - 10
