| 2/3 – 1/2 x | = 4/5 trả lời nhanh lên, mk đg cần gấp

`| 2/3 – 1/2 x|=4/5`

`=> 2/3 – 1/2 .x =4/5` hoặc `2/3 -1/2 x =(-4)/5`

`+,TH1:`

`2/3 – 1/2 .x =4/5`

`1/2 .x=2/3 – 4/5`

`1/2 .x=(-2)/15`

`x=(-2)/15 : 1/2`

`x= (-2)/15 .2`

`x=(-4)/15`

`+,TH2:`

`2/3 – 1/2 .x =(-4)/5`

`1/2 .x = 2/3 -(-4)/5`

`1/2 .x=22/15`

`x=22/15 .2`

`x= 44/15`

$\text{Vậy }$ `x= (-4)/15` hoặc `x=44/15`
