(3) d i rec t r i z (y - 7 = 0)

- 3 e d r^{2} c t zy + 21 e d r^{2} c t z = 0

Schritte zur Lösung

(3) d i rec t r i z (y - 7 = 0)

= (3) i e i d rrc t z (y - 7 \cdot 0 =)

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = (3) d i rec t r i z, b = y, c = 7 = 0

(3) d i rec t r i zy - (3) d i rec t r i z \cdot 7 = 0

(3) i e i d rrc t zy - (3) \cdot 7 i e i d rrc t z = 0
