Toán $\frac{1}{2}$ ( x-2 ) -2 ( 1- $\frac{1}{2}$ x ) =1 11/08/2021 By Josie $\frac{1}{2}$ ( x-2 ) -2 ( 1- $\frac{1}{2}$ x ) =1
Từ đề: `=> 1/2x – 1 – 2 + x = 1` `=> (1/2 x + x) – 1 – 2 = 1` `=> 3/2x – 3 = 1` `=> 3/2x = 4` `=> x = 4 : 3/2` `=> x = 4 × 2/3` `=> x = 8/3` (Chúc bạn học tốt) Trả lời
Từ đề:
`=> 1/2x – 1 – 2 + x = 1`
`=> (1/2 x + x) – 1 – 2 = 1`
`=> 3/2x – 3 = 1`
`=> 3/2x = 4`
`=> x = 4 : 3/2`
`=> x = 4 × 2/3`
`=> x = 8/3`
(Chúc bạn học tốt)
`1/2 (x-2)-2(1-1/2 x)=1`
`⇔1/2 x -1 -2 +x=1`
`⇔3/2 x=4`
`⇔x=8/3`
