Lösung

\frac{x}{7} = 4

x = - 28 or x = 28

Schritte zur Lösung

\frac{x}{7} = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{x}{7} = - 4 or \frac{x}{7} = 4

\frac{x}{7} = - 4 or \frac{x}{7} = 4

x = - 28 or x = 28

∣ - 7 a - 10 ∣ = - 10 a

∣ x - 1 ∣ + ∣ x + 7 ∣ = 8

∣ x + 2 ∣ = 4 + 2 x

x^{2} - 16 = x^{2} - 16

- 2 ∣ x + 3 ∣ = - 10
