|-1/2 x|=4

Lösung

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

x = - 8 or x = 8

Schritte zur Lösung

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

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

x = - 8 or x = 8

so l v e f or m, k = ∣ m ∣ + 3

∣ y - 1 ∣ = 36

∣ - 3 x - 1 ∣ - 7 = 18

∣ 2 x + 5 ∣ - 23 = - 23

∣ 4 - 3 x ∣ = 5
