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

∣ 5 x + 5 ∣ - 16 = 0

∣ - 5 y ∣ - 8 = 2

∣ 4 x + 5 ∣ = x + 6

∣ 4 x + 5 ∣ = x + 5

∣ 4 x + 5 ∣ = x + 3
