|x+1|=14

Lösung

∣ x + 1 ∣ = 14

x = - 15 or x = 13

Schritte zur Lösung

∣ x + 1 ∣ = 14

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 1 = - 14 or x + 1 = 14

x + 1 = - 14 or x + 1 = 14

x = - 15 or x = 13

∣ 6 v + 15 ∣ = 3

\frac{3 z + 5}{6} - 2 = 7

so l v e f or y, - 2 ∣ 2 y - 1 ∣ - 5 = - 7

x^{2} - 100 = 99

x^{2} - 22 x + 2 = 18
