|x+2|=10

Lösung

∣ x + 2 ∣ = 10

x = - 12 or x = 8

Schritte zur Lösung

∣ x + 2 ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 2 = - 10 or x + 2 = 10

x + 2 = - 10 or x + 2 = 10

x = - 12 or x = 8

s im pl i f y (\frac{2 x ^{4} y ^{2}}{4 x ^{2} y})^{3}

(6 x - 18)^{2} - 20 = - 25

y^{2} = 9

7 x + 15 = 3 (3 x - 7)

\frac{3}{4} - \frac{1}{3} z = \frac{1}{4}
