erweitern 15(3x-1)-7(x-1=2(1+9x))

Lösung

erweitern

15 (3 x - 1) - 7 (x - 1 = 2 (1 + 9 x))

38 x - 8 = 2 + 18 x

Schritte zur Lösung

15 (3 x - 1) - 7 (x - 1 = 2 (1 + 9 x))

= 15 (3 x - 1) - 7 (x - 1 \cdot 2 = (1 + 9 x))

15 (3 x - 1) : 45 x - 15

= 45 x - 15 - 7 (x - 1 = 2 (1 + 9 x))

- 7 (x - 1 = 2 (1 + 9 x)) : - 7 x + 7 = 2 + 18 x

45 x - 15 - 7 x + 7 = 2 + 18 x

45 x - 15 - 7 x + 7 : 38 x - 8

38 x - 8 = 2 + 18 x
