4 (6 - x - 2 (3 - x - 5 = 9 (5 - 2 x)))

4 \cdot 6 - 4 x + 8 x + 336 = 5 - 2 x

解答ステップ

4 (6 - x - 2 (3 - x - 5 = 9 (5 - 2 x)))

= 4 (6 - x - 2 (3 - x - 5 \cdot 9 = (5 - 2 x)))

拡張

4 (6 - x - 2 (3 - x - 5 = 9 (5 - 2 x))) : 4 \cdot 6 - 4 x - 4 \cdot 2 (3 - x - 5 \cdot 9 = (5 - 2 x))

= 4 \cdot 6 - 4 x - 4 \cdot 2 (3 - x - 5 \cdot 9 = (5 - 2 x))

拡張

- 4 \cdot 2 (3 - x - 5 \cdot 9 = (5 - 2 x)) : 8 x + 336 = 5 - 2 x

4 \cdot 6 - 4 x + 8 x + 336 = 5 - 2 x
