x = - 9 or x = 9

Schritte zur Lösung

∣ - 4 x ∣ = 36

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 4 x = - 36 or - 4 x = 36

- 4 x = - 36 or - 4 x = 36

x = - 9 or x = 9

x^{2} + 7 x - 1 = ∣ x + 2 ∣ + 9

∣ 16 x + 12 ∣ = 8

∣ 6 - 2 x ∣ + 7 = 12 x + 7

∣ x + 3 ∣ = 6

∣ x + 6 ∣ + 3 = 16
