erweitern 2((3r-s)=5(s+2t)-4(2t+s))

Lösung

erweitern

2 ((3 r - s) = 5 (s + 2 t) - 4 (2 t + s))

6 r - 2 s = - 3 s - 6 t

Schritte zur Lösung

2 ((3 r - s) = 5 (s + 2 t) - 4 (2 t + s))

= 2 (5 = (3 r - s) (s + 2 t) - 4 (2 t + s))

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = 2, b = (3 r - s) = 5 (s + 2 t), c = 4 (2 t + s)

2 (3 r - s) = 5 (s + 2 t) - 2 \cdot 4 (2 t + s)

Vereinfache

2 (3 r - s) = 5 (s + 2 t) - 2 \cdot 4 (2 t + s) : 6 r - 2 s = - 3 s - 6 t

6 r - 2 s = - 3 s - 6 t
