x = - 7 or x = 21

Schritte zur Lösung

∣ x - 7 ∣ = 14

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 7 = - 14 or x - 7 = 14

x - 7 = - 14 or x - 7 = 14

x = - 7 or x = 21

\frac{1}{4} (p + 3) - \frac{2}{5} (p + 1) = - 1

3 x^{2} - 9 = 0

f a c t or x^{2} - 4 x - 45

11 = \frac{2}{3} (8 x + 12)

\frac{1}{x} + \frac{1}{x + 1} < \frac{2}{x + 4}
