x = 5 or x = 9

Schritte zur Lösung

∣ - 7 + x ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 7 + x = - 2 or - 7 + x = 2

- 7 + x = - 2 or - 7 + x = 2

x = 5 or x = 9

∣ 10 - 5 x ∣ = 20

∣ x - 8 ∣ = 2 x - 4

0 = ∣ 6 x - 3 ∣ - 21

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

∣ 6 x - 12 ∣ = 6
