|-m-8|=2

Lösung

∣ - m - 8 ∣ = 2

m = - 10 or m = - 6

Schritte zur Lösung

∣ - m - 8 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- m - 8 = - 2 or - m - 8 = 2

- m - 8 = - 2 or - m - 8 = 2

m = - 10 or m = - 6

∣ x - 3 ∣ + 9 = 7

∣ u ∣ = 7

∣ 2 x + 3 ∣ = ∣ x - 2 ∣

3 ∣ 3 x - 5 ∣ = 12

2 x - 3 = 7
