| 1/4 x-5|=8

Lösung

\frac{1}{4} x - 5 = 8

x = - 12 or x = 52

Schritte zur Lösung

\frac{1}{4} x - 5 = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{1}{4} x - 5 = - 8 or \frac{1}{4} x - 5 = 8

\frac{1}{4} x - 5 = - 8 or \frac{1}{4} x - 5 = 8

x = - 12 or x = 52

b^{2} = b^{2}

2 ∣ d ∣ + 3 = 5

x^{2} - 2 x = 12

∣ x + 3 ∣ = 2 x - 7

∣ x - 5 ∣ = 2 x - 1
