Lösung

4 - \frac{r}{7} = 5

r = - 7 or r = 63

Schritte zur Lösung

4 - \frac{r}{7} = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 - \frac{r}{7} = - 5 or 4 - \frac{r}{7} = 5

4 - \frac{r}{7} = - 5 or 4 - \frac{r}{7} = 5

r = - 7 or r = 63

∣ - 5 y + 9 ∣ = 2 y

- ln ∣ 1 - y ∣ = ln (x) + c

3 ∣ 4 x - 8 ∣ = 9

∣ 4 v + 8 ∣ = 4

12 = ∣ - 9 y ∣
