|(2x-5)/7 |=3

Lösung

\frac{2 x - 5}{7} = 3

x = - 8 or x = 13

Schritte zur Lösung

\frac{2 x - 5}{7} = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{2 x - 5}{7} = - 3 or \frac{2 x - 5}{7} = 3

\frac{2 x - 5}{7} = - 3 or \frac{2 x - 5}{7} = 3

x = - 8 or x = 13

\frac{y}{2} + \frac{4}{5} \leq 3

- \frac{1}{2} c + 26 < 22

f a c t or 6 x^{2} + 24 x - 126

2 x^{2} + 2 = 12
