|x-4|=0.01

Lösung

∣ x - 4 ∣ = 0.01

x = 3.99 or x = 4.01

Schritte zur Lösung

∣ x - 4 ∣ = 0.01

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 4 = - 0.01 or x - 4 = 0.01

x - 4 = - 0.01 or x - 4 = 0.01

x = 3.99 or x = 4.01

\frac{x}{2} + 5 = x

s im pl i f y \frac{- 5 + 2 i}{3 i}

- 3 x < 6

(x + 7) (x - 9) = 25

7 - \frac{x}{12} = 9
