|m+10|=4

Lösung

∣ m + 10 ∣ = 4

m = - 14 or m = - 6

Schritte zur Lösung

∣ m + 10 ∣ = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

m + 10 = - 4 or m + 10 = 4

m + 10 = - 4 or m + 10 = 4

m = - 14 or m = - 6

∣ a + 2 ∣ - 3 = 5

∣ 2 x + 2 ∣^{2} = 5

2 x^{2} - 3 - x = 3

∣ x - 8 ∣ = 16

so l v e f or y, x + ∣ y ∣ = 2 y
