Lösung

\frac{x + 1}{2} = 4

x = - 9 or x = 7

Schritte zur Lösung

\frac{x + 1}{2} = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{x + 1}{2} = - 4 or \frac{x + 1}{2} = 4

\frac{x + 1}{2} = - 4 or \frac{x + 1}{2} = 4

x = - 9 or x = 7

0 = ∣ x ∣

∣ n - 6 ∣ + 9 = 16

∣ 4 x + 5 ∣ = 19

0 = ∣ 3 c ∣

∣ 7 x - 3 ∣ + 3 = 5
