|4+8x|=5

Lösung

∣ 4 + 8 x ∣ = 5

x = - \frac{9}{8} or x = \frac{1}{8}

Dezimale

x = - 1.125, x = 0.125

Schritte zur Lösung

∣ 4 + 8 x ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 + 8 x = - 5 or 4 + 8 x = 5

4 + 8 x = - 5 or 4 + 8 x = 5

x = - \frac{9}{8} or x = \frac{1}{8}

∣ x ∣ + 2 = 10

x^{2} - 6 x - 2 ∣ x - 3 ∣ = - 6

x^{2} + 4 ∣ x ∣ - 12 = 0

- 6 ∣ r ∣ = - 7

so l v e f or x, ∣ 3 x + 12 ∣ = 9
