Lösung

∣ 3 x + 12 ∣ = 18

x = - 10 or x = 2

Schritte zur Lösung

∣ 3 x + 12 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x + 12 = - 18 or 3 x + 12 = 18

3 x + 12 = - 18 or 3 x + 12 = 18

x = - 10 or x = 2

\frac{5}{9} m - \frac{3}{7} = \frac{1}{4}

∣ x + 1 ∣ = 6

\frac{4 h - ( 21 - 8 h )}{3} = \frac{15 + 6 ( h - 1 )}{2}

\frac{x}{2} + \frac{x}{3} - 1 = \frac{x}{6} + 3
