|2h-3|=8

Lösung

∣ 2 h - 3 ∣ = 8

h = - \frac{5}{2} or h = \frac{11}{2}

Dezimale

h = - 2.5, h = 5.5

Schritte zur Lösung

∣ 2 h - 3 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 h - 3 = - 8 or 2 h - 3 = 8

2 h - 3 = - 8 or 2 h - 3 = 8

h = - \frac{5}{2} or h = \frac{11}{2}

20 = ∣ - 5 - 7 x ∣ 5

2 ∣ 3 x ∣ = 8

x^{2} + 6 x - 3 = 8

∣ x + 1 ∣ - 2 ∣ x - 1 ∣ = 0

x + ∣ x - 3 ∣ = 8
