|w-1|=7

Lösung

∣ w - 1 ∣ = 7

w = - 6 or w = 8

Schritte zur Lösung

∣ w - 1 ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

w - 1 = - 7 or w - 1 = 7

w - 1 = - 7 or w - 1 = 7

w = - 6 or w = 8

∣ 2 x - 3 ∣ + 3 = 3

∣ 2 x - 12 ∣ = 10

∣ - 7 x ∣ = 21

8 = ∣ s ∣ - 2

0 = - ∣ g + 5 ∣
