|x-4|=2

Lösung

∣ x - 4 ∣ = 2

x = 2 or x = 6

Schritte zur Lösung

∣ x - 4 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 4 = - 2 or x - 4 = 2

x - 4 = - 2 or x - 4 = 2

x = 2 or x = 6

- 3 - 3 (1 + 3 n) = - 42

\frac{1}{6} (12 - 6 x) = 5 (x + 4)

\frac{1}{5} < \frac{2 x - 4}{3} < 6

[- \frac{29}{24} - (- \frac{13}{48})] - (- \frac{5}{6})

x^{2} + 5 x + 3 = 0
