✔ 最佳答案
14 - 2(4x - 2)∕3 = 2 2(4x - 2)∕3 =14-2
2(4x - 2)∕3=12
2(4x - 2)=12x3
2(4x - 2)=36
(4x - 2)=36/2
4x - 2=18
4x=18+2
4x=20
x=20/4
x=5
所以x係等於5
詳唔詳細?

14 - 2(4x - 2)∕3 = 2
14 - 2 = 2 (4x - 2)∕3
12 = 8x - 4∕3
12 x3=8x-4
36+4=8x
40/8=x
x=5
希望可以幫到你(^_^)

14-2(4X-2) / 3 = 2
14 - 2(4x-2) / 3 = 2 左 右 兩 邊 同 時 乖 3
42 - 2(4x - 2) = 6
42 - 8X + 4 = 6
46 - 8X = 6
46- 6 = 8X
40 = 8X
X = 8
