✔ 最佳答案
將所有有x的group埋一齊，同將-1/5調去右邊like this: (1/2-1/3-1/4)x=1/6+1/5
-1/12x=11/30
x=(11/30)(-12) <-- 呢度-1/12x調過去時要顛倒, 變成-12
x= - 22/5

This question is not clearly defined.
1/2x = 1/(2x)
If 1/2x means half of x, it should be (1/2)x
1/(2x) - 1/(3x) - 1/(4x) - 1/5 = 1/6
x = -5/22
(1/2)x – (1/3)x – (1/4)x - 1/5 = 1/6
x = -22/5
1/2x = 1/(2x)
If 1/2x means half of x, it should be (1/2)x
1/(2x) - 1/(3x) - 1/(4x) - 1/5 = 1/6
x = -5/22
(1/2)x – (1/3)x – (1/4)x - 1/5 = 1/6
x = -22/5

1/2x - 1/3x - 1/4x - 1/5 = 1/6
x=6
