|(x+8)/3 |=7

Lösung

\frac{x + 8}{3} = 7

x = - 29 or x = 13

Schritte zur Lösung

\frac{x + 8}{3} = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{x + 8}{3} = - 7 or \frac{x + 8}{3} = 7

\frac{x + 8}{3} = - 7 or \frac{x + 8}{3} = 7

x = - 29 or x = 13

∣ x + 3 ∣ = - x - 3

∣ u ∣ = 3, - 2

16 = 4 - ∣ w - 1 ∣

x^{2} - 6 x + 4 = 4

8 = ∣ m + 1 ∣
