Lösung

∣ 5 - b ∣ = 12

b = - 7 or b = 17

Schritte zur Lösung

∣ 5 - b ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 - b = - 12 or 5 - b = 12

5 - b = - 12 or 5 - b = 12

b = - 7 or b = 17

∣ 5 - 2 x ∣ = 18

- 2 ∣ 7 - 9 c ∣ + 7 = - 15

20 = ∣ 9 - 4 y ∣

∣ 5 x - 2 ∣ = 13

∣ 5 x - 7 ∣ + 1 = 3 x
