| 1/2 x-5|=11

Lösung

\frac{1}{2} x - 5 = 11

x = - 12 or x = 32

Schritte zur Lösung

\frac{1}{2} x - 5 = 11

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{1}{2} x - 5 = - 11 or \frac{1}{2} x - 5 = 11

\frac{1}{2} x - 5 = - 11 or \frac{1}{2} x - 5 = 11

x = - 12 or x = 32

∣ 15 - 5 x ∣ = 70

∣ 3 x + 6 ∣ + 3 = 21

∣ a - 4 ∣ = 0

0 = 3 ∣ x + 4 ∣ - 4

∣ 2 x + 1 ∣ - 5 = 8
