|-5+x|=3

Lösung

∣ - 5 + x ∣ = 3

x = 2 or x = 8

Schritte zur Lösung

∣ - 5 + x ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 5 + x = - 3 or - 5 + x = 3

- 5 + x = - 3 or - 5 + x = 3

x = 2 or x = 8

∣ x ∣ - 8 = - 5

∣ 5 b + 9 - 2 b ∣ + 9 = 6 b

∣ 9 - 2 x ∣ = 1

∣ 3 x - 5 ∣ - 9 = 2

\frac{1}{4} x - 5 = 8
