|5x-10|=15

Lösung

∣ 5 x - 10 ∣ = 15

x = - 1 or x = 5

Schritte zur Lösung

∣ 5 x - 10 ∣ = 15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 x - 10 = - 15 or 5 x - 10 = 15

5 x - 10 = - 15 or 5 x - 10 = 15

x = - 1 or x = 5

\frac{x ^{2}}{4} - \frac{x}{1} = \frac{5}{4}

- x^{2} = 0

169 = (x - 7)^{2}

s im pl i f y (a^{8})^{\frac{3}{2}}

144 - 16 t^{2} = 0
