x = - 22 or x = 16

Schritte zur Lösung

∣ x + 3 ∣ = 19

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 3 = - 19 or x + 3 = 19

x + 3 = - 19 or x + 3 = 19

x = - 22 or x = 16

∣ 7 r - 3 ∣ = ∣ 4 r + 15 ∣

∣ 5 x - 9 ∣ - 8 = - 1

\frac{∣ x + 1 ∣}{3} = 3

2 ∣ 5 x - 4 ∣ - 5 = 9

∣ 7 x ∣ = 12
