|h+1|=6

Lösung

∣ h + 1 ∣ = 6

h = - 7 or h = 5

Schritte zur Lösung

∣ h + 1 ∣ = 6

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

h + 1 = - 6 or h + 1 = 6

h + 1 = - 6 or h + 1 = 6

h = - 7 or h = 5

∣ x - 2 ∣ + 6 = 10

∣ 4 x + 6 ∣ = 8

∣ 4 x + 6 ∣ = 9

∣ 6 x + 2 ∣ + 12 = 7

so l v e f or y, ∣ y ∣ = 2 - 5 x
