2(7x-1)-3(3x-6)-5(11x+6)=196

解

2 (7 x - 1) - 3 (3 x - 6) - 5 (11 x + 6) = 196

x = - \frac{21}{5}

十進法表記

x = - 4.2

解答ステップ

2 (7 x - 1) - 3 (3 x - 6) - 5 (11 x + 6) = 196

拡張

2 (7 x - 1) - 3 (3 x - 6) - 5 (11 x + 6) : - 50 x - 14

- 50 x - 14 = 196

14

を右側に移動します

- 50 x = 210

以下で両辺を割る

- 50

x = - \frac{21}{5}
