|m-7|=12

Lösung

∣ m - 7 ∣ = 12

m = - 5 or m = 19

Schritte zur Lösung

∣ m - 7 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

m - 7 = - 12 or m - 7 = 12

m - 7 = - 12 or m - 7 = 12

m = - 5 or m = 19

s im pl i f y \frac{1}{2} - \frac{1}{16}

14 x^{2} - 5 x - 1 = 0

x^{6} + 13 x^{3} + 30 = 0

(x) (1.06) (70000 - x) (1.085) = 70000 + 5000

- x > - 4
