`1/2x + 2/3(x-2) = 1/3`
`=> 1/2x + 2/3x-4/3 = 1/3`
`=> 1/2x+2/3x = 1/3 + 4/3`
`=> 7/6x = 5/3`
`=> x = 10/7`
Vậy `x=10/7`
Answer
`1/2x + 2/3 . (x - 2) = 1/3`
`=> 1/2x + 2/3x - 4/3 = 1/3`
`=> (1/2x + 2/3x) - 4/3 = 1/3`
`=> 7/6x - 4/3 = 1/3`
`=> 7/6x = 1/3 + 4/3`
`=> 7/6x = 5/3`
`=> x = 5/3 : 7/6`
`=> x = 10/7`
Vậy `x = 10/7`
