x/(-3x-3)=-3(x+1)

解

\frac{x}{- 3 x - 3} = - 3 (x + 1)

x = - \frac{17}{18} + i \frac{35}{18}, x = - \frac{17}{18} - i \frac{35}{18}

解答ステップ

\frac{x}{- 3 x - 3} = - 3 (x + 1)

以下で両辺を乗じる:

- 3 x - 3

x = - 3 (x + 1) (- 3 x - 3)

解く

x = - 3 (x + 1) (- 3 x - 3) : x = - \frac{17}{18} + i \frac{35}{18}, x = - \frac{17}{18} - i \frac{35}{18}

x = - \frac{17}{18} + i \frac{35}{18}, x = - \frac{17}{18} - i \frac{35}{18}
